Is this really happening lets find out in todays episode? Electric vehicles are rapidly becoming popular, but some potential customers still remain hesitant. One of the main reasons is that charging an ev is time consuming, while drivers today are accustomed to filling their gas tanks in under five minutes. Electric vehicles, depending on the size and specifications of the battery, typically require at least 30 minutes to get 80 charged at the quickest charging stations out there. There were several companies that discovered rapid battery charging, so will charging electric cars ever be as fast as pumping gas? Slow charging times are holding back potential electric vehicle buyers, but new research suggests that a fast charging battery is feasible. New lithium ion battery materials are being developed as well as new, solid state batteries that are more stable. At quicker charging speeds, they could be able to achieve a recharge rate of 20 minutes or less. Meanwhile, a group of scientists recently designed a lithium battery prototype that can recharge more than 50 percent of its capacity in only three minutes under laboratory conditions and do so thousands of times without the battery significantly deteriorating. According to the researchers, this might open the way for batteries that can be fully recharged in as little as 10 minutes. So why are there still challenges in fast charging electric vehicle batteries? The first thing that must be understood is that thousands of lithium ion cells make up the batteries of modern electric vehicles with the capability of storing and releasing energy thousands of times.

Each of those cells consists of two electrodes, a metal cathode and a graphite anode separated by a liquid electrolyte. The speed at which lithium ions move from the cathode into the anode determines how quickly the battery charges, but just as placing blocks in a jenga tower hastily can cause the structure to become unstable if lithium is forced into the anode too fast problems start to arise. Lithium batteries can overheat at high charging speeds, leading them to deteriorate over time. More problematically lithium can start to build up upon the surface of the anode. Instead of entering it, a phenomenon known as lithium plating. Not only can that drastically reduce the batterys capacity. The lithium deposits eventually form filament, like structures known as dendrites once they start forming. Those dendrites can grow across the electrolyte, touch the cathode and create a short circuit causing the battery to catch fire or, worse, explode. Due to the issues with fast charging, all electric vehicle batteries have built in charging speed restrictions set by the cars on board charge ports a 350 kilowatt fast charging station. The most powerful public charger available in the us today might, in theory, be able to charge an audi e tron suvs 95 kilowatt hour battery in about 16 minutes. But the battery itself can only accept about 150 kilowatts of power at most placing its actual charging speed limit closer to 40 minutes. Currently, scientists and several companies have been developing batteries for electric vehicles to charge in a short time so which companies are these, and how can they do that? New research may be pushing these super batteries closer to reality.

Recently, a team led by harvard university materials scientist shin li designed a solid state, lithium metal battery cell that uses several different layers of materials in the electrode to arrest lithium dendrite growth. In the journal nature, the team described a prototype battery that could be charged in just 3 minutes, while retaining more than 80 of its capacity after 10 000 cycles. Typical electric vehicle batteries degrade by a similar amount after 1000 to two thousand cycles. The research is still at an early age. Lee says that a commercial version of this battery may be possible in about five years. If everything goes right, batteries capable of fully charging in five minutes have been produced in a factory for the first time, marking a significant step towards electric cars becoming as fast a charge as filling a petrol or diesel vehicles. The new lithium ion batteries were developed by the israel company stordot and manufactured by eve. Energy in china on standard production lines, store, dot has already demonstrated its extreme fast charging. Batteries in phones, drones and scooters, and the thousand batteries it has now produced are to showcase its technology to car makers and other companies. Daimler, bp, samsung and tdk have all invested in store dot, which has raised 130 million us dollars to date and was named a bloomberg new energy finance pioneer in 2020.. The batteries can be fully charged in five minutes, but this would require more high powered chargers than is used today.

Doran meyersdorf, ceo of storedot, said a 5 minute. Charging lithium ion battery was considered to be impossible, but we are not releasing a lab prototype. We are releasing engineering samples from a mass production line. This demonstrates it is feasible and its commercially ready. The store dot battery replaces graphite with semiconductor nanoparticles, into which ions can pass more quickly and easily. These nanoparticles are currently based on germanium, which is water, soluble and easier to handle in manufacturing. But stordots plan is to use silicon, which is much cheaper and expects these prototypes later this year. Next ion an eevee brand under the guangzhou automobile group or gac announced that its new electric vehicle model will be equipped with a graphene based battery that can be charged to the 80 level in just eight minutes and function for a thousand kilometers. In addition, neo often seen as teslas biggest rival in china unveiled its latest electronic sedan earlier this month, with an improved battery pack to support a 1 000 kilometer driving range is tesla feeling the pressure of designing a fast charging battery to compete with their rivals in An interview with mit technology review, teslas, cto jb straubel says that battery charging technology is going to get even quicker than it is now. He said its going to be hard, but i think we can get down to 5 or 10 minutes. He noted that the current superchargers, which deliver 120 kilowatts of electricity, seemed pretty crazy even 10 years ago.

One challenge of fast charging is that delivering power to a battery very rapidly can cause it to overheat, as we mentioned before, to avoid damaging the battery. The outside charger needs to communicate with the electronics that monitor the state of the batteries, including their voltage and temperature, and quickly adjust charging rates accordingly. To do that kind of charging. Everything has to be designed and working in perfect synchrony straubel says achieving five minute. Charges will require not only further improving the charging system, but also improving the interface with the electrical grid, as it is only some places on the grid can handle 120 kilowatt charging. But straubel says that tesla plans to get around these problems by equipping supercharging stations with solar panels and batteries. In conclusion, electric vehicles are an important part of an action to tackle the climate crisis, but running out of charge during a journey is a worry for any driver. Therefore, electric vehicle manufacturers need to develop batteries that can be quickly charged in a short time in the future. A 5 minute fast charge battery for electric vehicles will become a reality, possibly even faster, and that brings us to the end of todays video.
