First prototype battery with five minutes charge receivedJanuary 19, 2021
The battery can already be produced on existing production lines.
The Israeli company StoreDot received the first prototypes of battery cells, from which you can assemble a battery for an electric vehicle with a full charge time of five minutes. Interestingly, they are made on the commercial line of a Chinese partner, where conventional lithium-ion power sources are assembled.
StoreDot technology is based on replacing graphene in the anode with metalloidal nanoparticles. Now the company uses a rather rare germanium for this, but in the future it plans to switch to cheaper silicon. Prototypes with silicon will appear before the end of the year, and will be comparable in price to current lithium-ion batteries. In the meantime, StoreDot has several prototypes of batteries, and they were not manufactured in a laboratory, but on a commercial cell production line of its partner, China’s EVE Energy.
StoreDot’s partners include oil and gas BP, Daimler, Samsung and Japan’s TDK. The total investment in the startup was $ 130 million.
The pouch-bags are UN 38.3 certified. Like conventional lithium-nickel-cobalt-manganese (lithium-nickel-cobalt-manganese) or NCA (lithium-nickel-cobalt-aluminum) batteries, they have undergone rigorous stress testing to ensure transportability. The main advantage of StoreDot batteries is charging time. The power source, which will provide a mileage of 480 kilometers, will be completely filled in five minutes – but only from very powerful terminals. And by 2025, StoreDot plans to release batteries that will give an additional 160 kilometers in the same time, even when using existing stations. For comparison: Hyundai promises that the Ioniq 5 will increase the power reserve by 100 kilometers in five minutes.
Information about breakthroughs on the battery front appears more and more often, but a number of manufacturers, meanwhile, are interested in extending the life of fuel engines. Among them is Porsche, which, with the support of the Chilean government, will build the world’s first commercial synthetic methane and gasoline plant in the south of the country. The fuel will be used in racing cars as well as in Porsche Experience centers. But in the future, the company would like to transfer serial sports cars to synthetics.
