Car batteries that can be fully charged in five minutes have rolled off the production line for the first time. “The bottleneck for extra fast charging is no longer the battery.“
The new lithium-ion batteries were developed by the Israeli company StoreDot and are produced in China. StoreDot is working on technology to enable even faster charging and also makes fast rechargeable batteries for smartphones, drones and scooters.
Daimler, BP, Samsung and TDK have all invested StoreDot, which has raised $ 130 million (EUR 107 million) to date. In 2020, the company was crowned Bloomberg New Energy Finance Pioneer.
Their new car battery can be fully charged in five minutes, though it requires much more powerful chargers than those currently in use. By 2025, StoreDot wants to deliver batteries that can drive 160 kilometers after just five minutes of charging.
“The biggest obstacle to the use of electric vehicles is no longer the cost, but the fear of accessibility,” Doron Myersdorf, CEO of StoreDot, told the UK newspaper The Guardian. “You are either afraid that you will get stuck on the highway or that you will have to spend two hours in a charging station. But if the driver’s experience is exactly the same as refueling a petrol car, this fear disappears. ”
“A lithium-ion battery that can be recharged in five minutes was considered impossible,” explains Myersdorf. “But we don’t release a prototype from a laboratory, we release sample samples from a production line. This shows that it is feasible and that it is commercially ready. ”
The same cost
The StoreDot battery replaces graphite, which is used in current lithium-ion batteries, with semiconductor nanoparticles in which the ions can transfer more quickly and easily. According to Myersdorf, the cost of the new battery will be the same as that of the current lithium-ion batteries.
“The bottleneck for extra fast charging is no longer the battery,” he says. According to Myersdorf, the next step is to improve the charging stations and the electricity networks that power them.
