As it turns out, Tesla, and its battery partner Panasonic, started production of cells for qualification at the plant in December, but today, it confirmed the start of “mass production” of the new battery cell, which will enable several of Tesla’s new products, including the Model 3. The new cell is called ‘2170’ because it’s 21mm by 70mm. It’s thicker and taller than the previous cell that Tesla developed with Panasonic, which was in an ‘18650’ cell format. Tesla CEO Elon Musk has been boasting about the new cell over the past few month. He said that it’s the “highest energy density cell in the world and also the cheapest”.

New method increases energy density in lithium batteries:technology, technology news, newtech. technology videos:https://youtu.be/KabEsCJGYaw New method increases energy density in lithium batteries Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method to increase the energy density of lithium (Li-ion) batteries. He has built a trilayer structure that is stable even in ambient air, which makes the battery both longer lasting and cheaper to manufacture. The work, which may improve the energy density of lithium batteries by 10-30%, is published online in Nano Letters. "When lithium batteries are charged the first time, they lose anywhere from 5-20% energy in that first cycle," says Yang. "Through our design, we've been able to gain back this loss, and we think our method has great potential to increase the operation time of batteries for portable electronics and electrical vehicles." During the first charge of a lithium battery after its production, a portion of liquid electrolyte is reduced to a solid phase and coated onto the negative electrode of the battery. This process, usually done before batteries are shipped from a factory, is irreversible and lowers the energy stored in the battery. The loss is approximately 10% for state-of-the-art negative electrodes, but can reach as high as 20-30% for next-generation negative electrodes with high capacity, such as silicon, because these materials have large volume expansion and high surface area. The large initial loss reduces achievable capacity in a full cell and thus compromises the gain in energy density and cycling life of these nanostructured electrodes. The traditional approach to compensating for this loss has been to put certain lithium-rich materials in the electrode. However, most of these materials are not stable in ambient air. Manufacturing batteries in dry air, which has no moisture at all, is a much more expensive process than manufacturing in ambient air. Yang has developed a new trilayer electrode structure to fabricate lithiated battery anodes in ambient air. In these electrodes, he protected the lithium with a layer of the polymer PMMA to prevent lithium from reacting with air and moisture, and then coated the PMMA with such active materials as artificial graphite or silicon nanoparticles. The PMMA layer was then dissolved in the battery electrolyte, thus exposing the lithium to the electrode materials. "This way we were able to avoid any contact with air between unstable lithium and a lithiated electrode," Yang explains, "so the trilayer-structured electrode can be operated in ambient air. This could be an attractive advance towards mass production of lithiated battery electrodes." Yang's method lowered the loss capacity in state-of-the-art graphite electrodes from 8% to 0.3%, and in silicon electrodes, from 13% to -15%. The -15% figure indicates that there was more lithium than needed, and the "extra" lithium can be used to further enhance cycling life of batteries, as the excess can compensate for capacity loss in subsequent cycles. Because the energy density, or capacity, of lithium-ion batteries has been increasing 5-7% annually over the past 25 years, Yang's results point to a possible solution to enhance the capacity of Li-ion batteries. His group is now trying to reduce the thickness of the polymer coating so that it will occupy a smaller volume in the lithium battery, and to scale up his technique. "This three-layer electrode structure is indeed a smart design that enables processing of lithium-metal-containing electrodes under ambient conditions," notes Hailiang Wang, assistant professor of chemistry at Yale University, who was not involved with the study. "The initial Coulombic efficiency of electrodes is a big concern for the Li-ion battery industry, and this effective and easy-to-use technique of compensating irreversible Li ion loss will attract interest."

As JCESR scientists work to develop lighter and less expensive chemistries than those used in current lithium-ion batteries, lithium-sulfur shows tremendous promise. However, current lithium-sulfur batteries require an excessive amount of electrolyte to achieve moderate cycle life. This perspective presents an alternate approach of using “sparingly solvating” electrolytes, which could move us closer to long-lived, high energy density lithium-sulfur batteries.

By Austin Anderson, Lewei He, Kiri Nicholson, and Brooke Noeska Adoption of electric cars has been on the rise for the past decade due to the substantial advances that have been made by improvement of technology. The greatest challenges regarding electric cars are their batteries. Finding a balance between battery life, weight, rechargeability, and cost has proven to be a significant issue. This video focuses on lithium-ion batteries used in electric vehicles. First, we provide a quick survey of electric vehicle designs. We then discuss chemistry, physics, and material science behind basic design of lithium-ion batteries. Next, we look at challenges that electric vehicles and the batteries face, which is the balance between adequate energy storage and weight of the battery. How do we solve these challenges? The answer to this question lies within the material science paradigm triangle, which looks at property, processing, and structure. One key aspect in performance of the battery is the use of silicon versus graphite anodes, in which lithium ions are absorbed. Considering properties, graphite is more stable while silicon can absorb more ions, although they sometimes absorb too much and fail due to the mechanical stress. Considering processing, silicon films as thin as 20nm can absorb nearly the maximum amount of ions while limiting the amount of load the ions create. Finally, in a structural view, research has shown that small amount of tin in silicon anodes can greatly enhance capacity. Similarly, silicon-graphene anodes are another option with improvements in capacity and stability. In this perspective, the way to improve performance is clear: thinner silicon sheets with small amount of tin. Lithium ion batteries hold a lot of advantages over other types of power sources. Compared to gasoline, vehicles produce less emission by using power that may be generated by renewable and nuclear energy. Compared to other batteries, lithium-ion provides high energy density by weight, relatively low amount of toxic and hazardous elements, and a good cycle durability. The future of electric vehicles is immense, and with advancements in material science, lithium-ion batteries will likely continue to provide the energy that not only drives cars, but also drives the growth of the market of electric vehicles.

Panasonic Hints At ‘Beyond Lithium’ Technology For EV Battery Improvements. Lithium-ion batteries represent a landmark technology that has made the current generation of electric vehicles possible. However, the day of their demise, while it still lies years in the future, is within view. Lithium-ion chemistries have a certain maximum energy density, dictated by those pesky laws of physics, and today’s batteries are not so far from that theoretical maximum. If drivers keep demanding longer ranges and faster charging times, then a better technology will have to be found. Safety is also an issue. The spectacular explosions and fireballs that some documentary-makers revel in are not the norm (when was the last time your phone or computer caught fire?), but Li-ion batteries do have to be handled carefully, and necessary safety features add complexity and cost to battery packs. A new chemistry that is safer could also prove to be cheaper. Researchers around the world are working on “beyond lithium” projects, and the past year has seen several significant breakthroughs. Of course, advances in the lab take years to make their way to the marketplace, but if and when one of these promising technologies can be commercialized, we could see game-changing improvements in the performance and cost of EVs. One technology that’s been getting a tremendous amount of attention from researchers is the solid-state battery, which uses a solid electrolyte instead of the liquid electrolyte used today. Solid-state batteries could theoretically have double the energy density of current batteries, and last several times longer. They also use a non-flammable electrolyte – usually glass, polymer, or a combination – so they would eliminate the safety issues that plague Li-ion cells. Lithium-air batteries likewise could offer far greater energy density – maybe as much as 10 times more – but they suffer from poor cycle life. In 2015, Cambridge scientists wowed the battery world with an announcement that they had demonstrated a highly efficient and long-lasting lithium-oxygen battery. Alas, researchers from several universities and national labs have since been unable to duplicate the original results. Other promising battery chemistries use other elements in place of lithium. Sodium batteries powered Jules Verne’s futuristic submarine in “20,000 Leagues Under the Sea.” More recently, in 2015, researchers created a prototype sodium-ion battery in the industry-standard 18650 cylindrical format. According to a recent article in the Nikkei Asian Review, battery research has seen a big shift in recent years. At one time, nearly half of the presentations at the Battery Symposium in Japan were about fuel cells and Li-ion battery cathode materials. But since 2012, these topics have been supplanted by presentations about solid-state, lithium-air and non-lithium batteries.

"Physics of next generation batteries" Martin Z. Bazant, MIT - Visiting Professor, Materials Science & Engineering, SUNCAT Center, Stanford University Energy Seminar - April 18, 2016 Next generation batteries must achieve significant reductions in cost (for stationary energy storage) or weight (for electrified transportation). In this effort, the chemistry of new battery materials has received the most attention, but the physics of convection, electromigration, and phase transformations are also critical to understand and exploit for engineering design. For example, flow batteries decouple energy (in tanks) and power (in the stack) and exploit convection to cycle ultra-low-cost reactants, such as zinc-iron and hydrogen-bromine, at high rates, even without expensive membranes. In principle, high energy density can be achieved in the same way in lithium-bromine-oxygen flow batteries. Phase transformations must also be controlled, in Li-ion and Li-metal batteries. In particular, most future battery concepts for transportation assume a rechargeable lithium metal anode, which must overcome morphological instabilities to achieve stable cycling (free of dendrites and without excessive SEI growth). Some progress on all of these problems will be presented.

A Google TechTalk, 2/9/18, presented by Andreas Hintennach ABSTRACT: Ever since the development of lithium-ion batteries the spirit of invention has mainly lead to an evolution of existing materials. With the focus on olivine and Nickel- and cobalt based materials the energy densities, power densities and ageing mechanisms could be investigated over the years and support the understanding of the underlying mechanisms of electrochemical energy storage and conversion. With increasing numbers of cells being used in the world the need of a post Lithium-Ion technology emerges due to a limited availability of highly pristine nickel and cobalt and increasing need for recycling, environmental protection and overall energy efficiency. Nevertheless there is still an ongoing and very promising approach for e. g. novel stoichiometries of NMC materials, olivine materials, and nickel-rich materials with can significantly increase the energy density. But due to some limitation in the field of raw materials availability, accessibility, and sustainability, low-cobalt or cobalt-free materials are of very high interest, too. For example LMR (LNMO) can be an ideal candidate. Due to the very high reactivity and potential (i. e. 4.5 V) these materials require highly stable electrolytes. Finally, lithium-sulphur can lead to a highly recyclable, environmentally friendly system. Having a silicon-based anode (greater than 85 % Si) included both volumetric and gravimetric energy density can mean an interesting alternative to metal-oxide based materials. With the increased energy density, safety becomes a more and more important aspect in thermodynamic and kinetic investigations of these materials. This aspect can lead to the development of non-flammable electrolytes or solid state cells. Solid state cells are a very different but highly promising approach. Having a solid-solid interphase between electroactive materials and electrolyte the chemicals mechanisms significantly change to solid state chemistry rather than solid-organic interphases chemistry. All types of novel chemistries exhibit very different chemical mechanisms which require specific synthetically work, e. g. with the support of numerical simulation, for electrolytes, additives, binders, carbon materials, and even the surfaces of the electro-active materials itself. Understanding these mechanisms is essential to further improve the life-time, efficiency, and hence, the sustainability of any kind of energy storage and conversion, but batteries in particular.

The success of electric vehicles depends largely on their energy storage system. Lithium-ion batteries currently feature the best properties to meet the wide range of requirements specific to automotive applications – high energy density, long lifetime, good power capabilities and low cost. However, the safety and reliability of lithium ion batteries can be problematic if they are not handled appropriately. Exposing lithium ion batteries to extremely high or low temperatures, voltages or excessive currents results in accelerated battery degradation and in the worst case, battery failure. This video looks at how we can improve the Battery Management System (BMS) of lithium-ion batteries by producing highly accurate degradation models which can estimate current useful battery capacity, power capabilities, prediction of the remaining battery life and prediction of battery failure and thus contribute to the accuracy of the BMS. -------------------------------------------------------------------------------------------------------- Video produced by Crustacean Studio - http://www.crustaceanstudio.com Research funded by the Engineering and Physical Sciences Research Council (EPSRC) and Jaguar Land Rover.

Holy smokes, these fumes! Chopping a (puffy and worn out) lithium polymer battery that is holding a 75% charge. I was interested in doing this to see what would happen to a pouch type battery when sliced by metal, like it might happen with cells used in a home built electric vehicle. These high power cells with relatively good energy density (120 to 130 Wh/kg) are good enough to power dragsters or hill climbers. But using them one will have to build sturdy enclosures, and most importantly arrange for venting that would allow fumes to escape and not kill the pilot before getting out/being pulled out. Interesting in this context is to see what the voltage does: It's not at all instantly gone, but still lurks for some time before the battery desintegrates enough to make it go to zero. In this case, there's no big fire, but enough smoldering to cause a lot of trouble if this was a large pack. Potentially related: the 2014 crash of Malaysia Airlines Flight 370 might have to do with fumes from damaged lipo batteries, here are some links: http://www.dailymail.co.uk/news/article-2586308/Missing-jet-WAS-carrying-highly-flammable-lithium-batteries-CEO-Malaysian-Airlines-finally-admits-dangerous-cargo.html http://www.airtrafficmanagement.net/2014/03/lithium-cargo-clue-to-fate-of-mh370/ I'm copying one of my own replies to comments below, to further explain what, and why, I'm doing this: "....doing extreme tests like this is actually a fairly common thing. For example, if you look into the Boeing Dreamliner battery issue, you'll sooner or later run into videos about a company that was on contract for Boeing, testing cells. They tested a lot of cells. And what did they do? Amongst other things, they took a gun and fired at cells, in different positions, size, state of charge, and whatnot. And where did they do that? Right out there in the desert somewhere in Arizona or Nevada (I don't remember exactly where). They would put the battery on a rock, count back a few paces, ready, aim and...poof. Flames, explosions, the whole nine yards. You think that they are the only ones doing tests so cruelly? Nope. Any company incorporating these batteries into something they sell will do such tests, or have somebody else do it for them. I would not put my money on many testers having filters and scrubbers to deal with the fumes. Sad, but reality. And now, why am I doing this? Well, there are many people out there who, like me, use these batteries without ever really seeing what happens... "if". And if you think the "if" could never be something that needs an axe cutting a cell in half, again you'd be wrong. I have seen a bicycle trailer with a sheet metal box and a battery inside that rolled over, collapsed, and partially cut into a lipo pack. Poofed and burned, but no camera was there. Had the guy known what can happen, he might have taken a bit more time to build a sturdier box. Insulate it. Fasten the battery inside. And so on, there's really no end to it. It might all seem wrong to you, but there is a very good reason to do these things. Feel free to buy an electric car down the line a few years from now from a company that never did extreme tests. I won't. I want to know. Even if it's just for my own projects. Ignorance is not bliss."

1. High energy density: The much greater energy density is one of the chief advantages of a lithium ion battery or cell. 2. Smaller and lighter: Li-ion battery is lighter than other rechargeable batteries in consideration of battery capacity. 3. Lithium ion cells is that their rate of self-discharge is much lower than that of other rechargeable cells such as Ni-Cad and NiMH forms. 4. Does not need prolonged priming when new. One regular charge is all that's needed. 5. Low maintenance: One major lithium ion battery advantage is that they do not require and maintenance to ensure their performance. 6. Quick charging: Li-ion battery is quicker to charge than other rechargeable batteries. 7. Variety of types available: There are several types of lithium ion cell available. This advantage of lithium ion batteries can mean that the right technology can be used for the particular application needed. 8. Specialty cells can provide very high current to applications such as power tools. 9. Longer lifespan: Li-ion battery can typically handle hundreds of charge-discharge cycles. Some lithium ion batteries loss 30 percent of their capacity after 1000 cycles while more advanced lithium ion batteries still have better capacity only after 5000 cycles.

*WARNING: Just a single 18650 cell has the potential to start a fire in your home / workplace. Building a battery is a very dangerous task that should only be done by an expert in electricity and electronics.* --------------------------------------------------------------------------------------------------- This 48V 21Ah (1kWh) Li-ion battery was designed and built to have a very high energy density being embedded into a small classical waterproof project case (2 litres) where it will allow to be used in extreme weather and terrain conditions while it will remain isolated from water or dirt. It has a raw maximum discharge current of 60A continuously (3kW) which as the electric vehicle target power output is 1.5kW maximum peak, electronics will limit to a maximum continuous discharge up to 35A (1.7kWnom) to secure a high life span and life cycling despite a future higher powered usage. In this video can be seen one of our safety implementations we designed and named "SPC" (safe parallel connection), where the construction improves integrity and safety and avoid dangerous situations if the battery would receive a hard impact / crush.

To make it simple, batteries work by moving electrons from a negatively charged material called an anode to a positively charged material called the cathode, and the device siphons off those electrons to power the device. For instance, nickel cadmium batteries use a nickel oxide cathode and a cadmium anode. Hence the name. This is a chemical process called oxidation that involves an electrolyte layer sandwiched between the electrodes. In the case of the nickel cadmium batteries, they use potassium hydroxide as the electrolyte. But this is a one-shot deal. The chemical reaction releases the electrons, but there’s no way to re-introduce electrons into the equation. So they’re not rechargeable. And for a world increasingly reliant on portable devices, that’s just not good enough. Enter Lithium-Ion batteries, which were developed in the 1970’s by John B. Goodenough. That’s his real name. That’s not a joke. Lithium ion batteries have a cathode made of lithium, duh, and an anode made of carbon, again with an electrolyte between the layers to facilitate the reaction. The difference is lithium will absorb more electrons, so it can be recharged. But it is still a chemical reaction, so it can only reintroduce those electrons at a certain charge rate. Super capacitors work differently. Instead of using a chemical reaction to make electrons flow, also called and electrochemical process, they use static electricity, or an electrostatic process. Now, capacitors have been in our computers for decades, and they work by holding opposite charges between two metallic plates separated by a dielectric material. Super capacitors, as you may have already figured out, are larger versions of capacitors that use a double layer to hold more energy. In fact they’re sometimes called double-layer capacitors. And the cool thing about them is that since the electricity is static and not chemical, there’s far less resistance to the charge. In fact, it’s almost instantaneous. The problem is, they don’t hold that much energy. You need a vast amount of surface area to hold enough energy to make them really useful. So Lithium Ion batteries are very energy dense, meaning they hold a lot more stored energy, but super capacitors are very power dense, meaning the transfer the energy much faster. If, theoretically, you could create super capacitors that could hold as much as a lithium ion battery, you’d have cell phones that could recharge in seconds and it would be good for the rest of the day. And dare we dream it? An EV car that fully charges faster than it takes to pump gas. There is one material that could make this dream a reality. It’s called graphene. Graphene is basically a one-atom thick lattice of carbon atoms that has some ridiculous properties. It’s 200 times stronger than steel, but incredibly light, biodegradable, biocompatible, meaning it can be used in the human body. They say it can be used to desalinate sea water, make space elevators, and form the basis for supercomputers, but for our purposes, it also happens to be one of the most electrically capacitive substances known to man. It has the same energy density as lithium ion batteries with the power density of super capacitors. And since it’s only one atom thick, you can pack a ton of surface area into a small space. With any luck, in the next 10-15 years, we’ll have super capacitor batteries that can handle energy densities at industrial scales giving us quick, plentiful electricity whenever we need it.

The chemistry used in the operation of a battery has a very important role in the improvement of many of its characteristics which can and should be improved, especially if it is intended to find the most suitable materials to optimize its operation. Many compounds have been tested, capable of intercalating, lithium-ion within its structure in a reversible manner, such as carbon and graphene materials of different types, cobalt-nickel-aluminum oxides, manganese compounds spinel type iron phosphates , titanium and lithium oxides, and many other compounds but none manages to improve all the necessary aspects in a battery, which make it stand out over the rest and when one aspect is improved, such as security others worsen in some cases, the cost of production or the density of energy or power obtained. It is therefore necessary to wait for some new breakthrough that will revolutionize the technology such as batteries lithium-air (also known as lithium-oxygen).

The pursuit of high energy density battery is at the heart of smartphones, wearable gadgets and electric vehicles. SolidEnergy revolutionized portable energy storage with the introduction of the “anode-free” lithium metal battery in 2014. It has 400 Wh/kg and 1200 Wh/L, twice the energy density of conventional Li-ion batteries, can safely deliver twice the amount of battery capacity for the same volume and same weight. And not just on paper, but in real batteries. SolidEnergy demonstrates that its 2Ah battery has the same capacity as the Apple iPhone 6 battery but only half the size. This doubling in energy density is enabled by two material platforms, dual-layer electrolyte and ultra-thin lithium metal anode, provide transformational energy density and safety across all rechargeable lithium batteries and can be seamlessly integrated into existing Li-ion manufacturing capability. The final applications include drones, watches & wearables, smart phones, and electric cars. The dream is to power people’s lives, whether they are communicating with loved ones on a phone or driving with family in an electric car. http:/www.solidenergysystems.com

An MIT spinout is preparing to commercialize a novel rechargable lithium metal battery that offers double the energy capacity of the lithium ion batteries that power many of today’s consumer electronics. Founded in 2012 by MIT alumnus, SolidEnergy Systems has developed an “anode-free” lithium metal battery with several material advances that make it twice as energy-dense, yet just as safe and long-lasting as the lithium ion batteries used in smartphones, electric cars, wearables, drones, and other devices. The battery essentially swaps out a common battery anode material, graphite, for very thin, high-energy lithium-metal foil, which can hold more ions — and, therefore, provide more energy capacity. Chemical modifications to the electrolyte also make the typically short-lived and volatile lithium metal batteries rechargeable and safer to use. Moreover, the batteries are made using existing lithium ion manufacturing equipment, which makes them scalable. In October 2015, SolidEnergy demonstrated the first-ever working prototype of a rechargeable lithium metal smartphone battery with double energy density, which earned them more than $12 million from investors. At half the size of the lithium ion battery used in an iPhone 6, it offers 2.0 amp hours, compared with the lithium ion battery’s 1.8 amp hours. SolidEnergy plans to bring the batteries to smartphones and wearables in early 2017, and to electric cars in 2018. But the first application will be drones, coming this November.

Lithium Ion batteries have a high energy density and are perfect for cyclic applications. They offer savings of up to 70% in volume and weight compared to traditional lead-acid batteries, with three times as many charging cycles (2000 full cycles). Another major benefit of the Mastervolt Li-ion battery is that it is equipped with a Battery Management System (BMS), which automatically compensates for any imbalance between the cells. This guarantees you a constant high capacity and longer battery lifespan. The Lithium Ion Ultra series includes integrated battery monitoring.

Linde’s Lithium-ion battery solution has high energy density and is more efficient than lead acid batteries. This energy density and level of efficiency results in a high usable capacity. this makes the battery more powerful than lead batteries and means it can be charged less often. Thanks to their chemical composition, Lithium-ion batteries are quick to charge and they are also suitable for intermediate charging as often as required, eliminating the need for a battery change. They features a long service lift and require no maintenance. Lithium-ion batteries also do not release any emissions and creates opportunities for savings across the life of the products.

Lithium ion cells are becoming more capable of delivering high power outputs for use in smaller applications such as this plane. Lithium ion cells are already used in land based applications, such as cars and bikes. However, the energy density (per mass) of the cell is far more essential for air based applications. The technology is still not quite there to be used in rotary aircraft (helicopters and drones) due to their high power consumption, but I'm sure it'll be possible soon!! ---------------------------------------------------------------------------------------------------------------------------------------- Support my videos via Patreon: https://www.patreon.com/tomstanton Huge thanks to the following Patrons for supporting me: Anthony Losego Bernard Gauweiler Craig rasch Dave Joubert ZoltÃ¡n VÃ©r Johan Lars Nielsen Christian Meinhardt KRCNZ Javier B Andoni Faris Elmasu Alper BahÃ§eliler Edvinas Festeris Martin aus Tirol Riley Penegor David MacDonald Ashleigh Peacock Charlie Garcia Marc Urben Jon Xuereb Stanton Frames: https://www.stantonframes.co.uk 3D Printer filament sponsored by 3D Printz UK: https://3dprintz.co.uk/ My Other Equipment: Main camera - http://amzn.to/2vlvlC6 Main lens - http://amzn.to/2gMrhru Main tripod - http://amzn.to/2tqRjBt Secondary Tripod - http://amzn.to/2t1NkMh Microphone - http://amzn.to/2uuv9n0 Audio recorder - http://amzn.to/2v3mjcG Banggood affiliate: https://www.banggood.com/?p=LT0710618750201406EK ---------------------------------------------------------------------------------------------------------------------------------------- Other Social Media Links: Instagram: https://www.instagram.com/stantonfpv/ FaceBook: https://www.facebook.com/Tom-Stanton-171292196234142/?fref=ts ----------------------------------------------------------------------------------------------------------------------------------------

Toshiba creates a battery: for cars that offers 320km of autonomy in 6 minutes of charge. One of the biggest problems of electric cars could be history thanks to a new Toshiba battery. The Japanese company has just presented a battery for electric cars that in only 6 minutes of loading offers 320 kilometers of use. The new generation of Toshiba car batteries, based on Ion-Lithium, is focused on changing one of the most well-known drawbacks of electric cars, charging times. Although companies like Tesla have managed to improve the speed of charge of their batteries, it still takes about an hour to have most of the battery charged. Depending on the type of electric car or even the type of battery that is selected, these vehicles could take several hours to charge. This is not an option for most people who come from a combustion car. Suzuki Solio Hybrid, one of the few electric cars that uses Toshiba batteries. Photo: Suzuki Motors. The new Toshiba battery offers high energy density and reduced charge time due to the use of titanium oxide doped with niobium. This element is also used in solar panels or even in superconducting images, such as those used in particle accelerators. After 5,000 charge / discharge cycles it maintains 90% of its original capacity. The battery is not yet in production, has been tested a prototype with a capacity of 50Ah, hence has extrapolated the results to what may be the future of this technology charging. Perhaps one of the most important details for the future of this battery is that after 5,000 charge / discharge cycles, it maintains 90% of its original capacity. This will result in an electric car would not have to change battery after a few years of use, even end up with rental programs. Toshiba hopes to start mass-producing this battery in 2019. For now only the electric cars of Suzuki and Mitsubishi use their batteries, also some brands of buses. Toshiba faces companies like Panasonic, associated with Tesla, which is nowadays one of the most important vehicle companies in the world.

What is this I am hearing about 18650 batteries and why should I care? I'll explain. In this video, I will provide a quick introduction to these little powerhouse batteries and why they are quickly becoming some of the most common batteries in the world. Not only do they provide more power and much higher energy density than older alkaline batteries but they last longer on the shelf and can be recharged over and over again. And they are safe to use as long as they have protection circuits and are not abused.

When will we have better batteries than lithium-ion for gadgets and electric vehicles? https://youtu.be/giRQAZJNXrA Many of us would be hard-pressed to spend a day without using a lithium-ion battery, the technology that powers our portable electronics. And with electric vehicles (EVs) and energy storage for the power grid around the corner, their future appears pretty bright. So bright that the iconic California-based upstart Tesla Motors stated that their newly announced residential Powerwall battery is sold out until mid-2016 and that the strong market demand could meet the capacity of their upcoming battery “gigafactory” of 35 gigawatt-hours per year – the daily electrical energy needs of 1.2 million US households. When released by Sony in the early 1990s, many considered lithium-ion batteries to be a breakthrough in rechargeable batteries: with their high operating voltage and their large energy density, they outclassed the then state-of-the-art nickel metal hydride batteries (NiMH). The adoption of the lithium-ion technology fueled the portable electronic revolution: without lithium-ion, the battery in the latest Samsung Galaxy smartphones would weigh close to four ounces, as opposed to 1.5 ounces, and occupy twice as much volume. Yet, in recent years lithium-ion batteries have gathered bad press. They offer disappointing battery life for modern portable devices and limited driving range of electric cars, compared to gasoline-powered vehicles. Lithium-ion batteries also have safety concerns, notably the danger of fire. This situation raises legitimate questions: What is coming next? Will there be breakthroughs that will solve these problems? Better lithium chemistries Before we attempt to answer these questions, let’s briefly discuss the inner mechanics of a battery. A battery cell consists of two distinct electrodes separated by an insulating layer, conveniently called a separator, which is soaked in an electrolyte. The two electrodes must have different potentials, or a different electromotive force, and the resulting potential difference defines the cell’s voltage. The electrode with the largest potential is referred to as the positive electrode, the one with the lowest potential as the negative electrode. During discharge, electrons flow through an external wire from the negative electrode to the positive electrode, while charged atoms, or ions, flow internally to maintain a neutral electrical charge. With rechargeable batteries, the process is reversed during charging. Lithium-ion batteries’ energy density, or the amount of energy stored per weight, has increased steadily by about 5% every year, from 90 watt-hours/kilogram (Wh/kg) to 240 Wh/kg over 20 years, and this trend is forecast to continue. It’s due to incremental refinements in electrodes and electrolyte compositions and architectures, as well as increases in the maximum charge voltage, from 4.2 volts conventionally to 4.4 volts in the latest portable devices. Picking up the pace of energy density improvements would require breakthroughs on both the electrodes’ materials and the electrolyte fronts. The biggest awaited leap would be to introduce elemental sulfur or air as a positive electrode and use metallic lithium as a negative electrode. In the labs Lithium-sulfur batteries could potentially bring a twofold improvement over the energy density of current lithium-ion batteries to about 400 Wh/kg. Lithium-air batteries could bring a tenfold improvement to approximately 3,000 Wh/kg, mainly because using air as an off-board reactant – that is, oxygen in the air rather than an element on a battery electrode – would greatly reduce weight. Both systems are intensively studied by the research community, but commercial availability has been elusive as labs struggle to develop viable prototypes. During the discharge of the sulfur electrodes, the sulfur can be dissolved in the electrolyte, disconnecting it from the electronic circuit. This reduces the amount of lithium that could be removed from the sulfur during the charge and hurts the overall reversibility of the system. To make this technology viable, critical milestones must be reached: improve the positive electrode architecture to better retain the active material or develop new electrolytes in which the active material is not soluble. The lithium-air battery, too, suffers from this difficulty of being repeatedly recharged as a result of problems caused by reactions between the electrolyte and air. Also, with both technologies, protection of the lithium electrode is an issue that needs to be solved.

Origins of Large Voltage Hysteresis in High-Energy-Density Metal Fluoride Lithium-Ion Battery Conversion Electrodes. Linsen Li et al (2016), Journal of the American Chemical Society http://dx.doi.org/10.1021/jacs.6b00061 Metal fluorides and oxides can store multiple lithium ions through conversion chemistry to enable high-energy-density lithium-ion batteries. However, their practical applications have been hindered by an unusually large voltage hysteresis between charge and discharge voltage profiles and the consequent low-energy efficiency (80%). The physical origins of such hysteresis are rarely studied and poorly understood. Here we employ in situ X-ray absorption spectroscopy, transmission electron microscopy, density functional theory calculations, and galvanostatic intermittent titration technique to first correlate the voltage profile of iron fluoride (FeF3), a representative conversion electrode material, with evolution and spatial distribution of intermediate phases in the electrode. The results reveal that, contrary to conventional belief, the phase evolution in the electrode is symmetrical during discharge and charge. However, the spatial evolution of the electrochemically active phases, which is controlled by reaction kinetics, is different. We further propose that the voltage hysteresis in the FeF3 electrode is kinetic in nature. It is the result of ohmic voltage drop, reaction overpotential, and different spatial distributions of electrochemically active phases (i.e., compositional inhomogeneity). Therefore, the large hysteresis can be expected to be mitigated by rational design and optimization of material microstructure and electrode architecture to improve the energy efficiency of lithium-ion batteries based on conversion chemistry.

What is LITHIUM-ION CAPACITOR? What does LITHIUM-ION CAPACITOR mean? LITHIUM-ION CAPACITOR meaning - LITHIUM-ION CAPACITOR definition - LITHIUM-ION CAPACITOR explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A lithium-ion capacitor (LIC) is a hybrid type of capacitor out of the family of the supercapacitors. Activated carbon is used as cathode. The anode of the LIC consists of carbon material which is pre-doped with lithium ions. This pre-doping process lowers the potential of the anode and allows a relatively high output voltage compared with other supercapacitors. In 1981, Dr. Yamabe of Kyoto University discovered PAS (polyacenic semiconductive) material in collaboration with Dr. Yata of Kanebo Co. It is prepared by the pyrolysis of phenolic resin at 400–700 °C. This amorphous carbonaceous material has excellent features as the electrode for high-energy-density rechargeable devices. The related patents were filed in the early 1980s by Kanebo Co., and started to develop towards the commercialization of PAS battery and lithium ion capacitor (LIC). The PAS battery was put in use in 1986, and LIC in 1991. A lithium-ion capacitor is a hybrid electrochemical energy storage device which combines the intercalation mechanism of a lithium ion battery with the cathode of an electric double-layer capacitor (EDLC). The packaged energy density of an LIC is approximately 20 Wh/kg generally four times higher than an EDLC and five times lower than a lithium ion battery. The power density however has been shown to match that of EDLCs able to completely discharge in seconds. The negative electrode (cathode) often employs activated carbon material at which charges are stored in an electric double layer that is developed at the interface between the carbon and the electrolyte. The positive electrode (anode) was originally made with lithium titanate oxide, but is now more commonly made with graphitic carbon material to maximize energy density. The graphitic electrode potential initially at -0.1 V versus SHE (standard hydrogen electrode) is lowered further to -2.8 V by the intercalation of lithium ions. This process step is referred to as doping and often takes place in the device between the anode and a sacrificial lithium electrode. The pre-doping process is critical to the device functioning as it can significantly affect the development of the Solid Electrolyte Interphase layer. Doping the anode lowers the anode potential and leads to a higher output voltage of the capacitor. Typically, output voltages for LICs are in the range of 3.8–4.0 V but are limited to a lower voltage of 1.8–2.2 V. If the voltage is brought any lower lithium ions will deintercalate more rapidly than they can be restored during normal use. Like EDLCs, LIC voltages vary linearly adding to complications integrating them into systems which have power electronics that expect the more stable voltage of batteries. As a consequence, LICs have a high energy density, which varies with the square of the voltage. The capacitance of the anode is several orders of magnitude larger than that of the cathode. As a result, the change of the anode potential during charge and discharge is much smaller than the change in the cathode potential. The electrolyte used in an LIC is a lithium-ion salt solution that can be combined with other organic components and is generally identical to that used in lithium ion batteries. A separator prevents direct electrical contact between anode and cathode.
