- An electric-car battery that can be charged in five minutes was announced on Monday.
- Standard electric-vehicle batteries take about 8 hours to fully charge.
- The faster-charging capability would make EVs more accessible to the general public.

An electric-car battery that can be charged in 5 minutes, the amount of time it takes to fill up a tank of gas, has been produced for the first time in a factory in China.
The new lithium-ion batteries were developed by Israeli company StoreDot and manufactured by Eve Energy in China. The company has produced 1,000 sample batteries compliant with Li-ion battery certifications, StoreDot announced Tuesday.
The samples will be used to showcase the company’s technology to potential buyers and investors looking to get a jump on the EV market, including BP, Daimler, Samsung Ventures, and TDK.
Faster-charging batteries would make electric vehicles more functional
For many drivers, electric cars are not feasible for long trips due to the amount of time it takes to charge the vehicles. Current electric-car batteries on the market can take anywhere from 30 minutes to 12 hours to charge, though a typical EV takes about 8 hours to charge from empty to full, according to PodPoint, an electric-vehicle-charger manufacturer.
Electric vehicles are a crucial part of Biden’s $2 trillion climate change plan, in which he wants an entirely green electric power grid by 2035 with cars running on electricity instead of gasoline. StoreDot’s new battery technology would make this green future more feasible, eliminating what CEO Doron Myersdorf calls electric vehicle’s biggest barrier: “range and charging anxiety.”
"Today's announcement marks an important milestone, moving XFC for the first time beyond innovation in the lab to a commercially-viable product that is scalable for mass production," Myersdorf said. in the press release. "We're on the cusp of achieving a revolution in the EV charging experience that will remove the critical barrier to mass adoption of EVs."
Electric cars average around 250 miles of driving capability per charge. With a battery that could charge faster, drivers would not be range bound and could take EVs on longer trips like any other conventional car.
While current lithium-ion batteries use graphite as an electrode, the StoreDot battery works faster by replacing graphite with semiconductor nanoparticles which allow ions to pass more easily and quickly. The company expects to replace this electrode with silicon, a much cheaper component, by the end of the year.
Tesla is also working on developing silicon electrodes.
Elon Musk has long been calling for faster charging speeds for electric cars
On Monday, Musk tweeted, "Battery cell production is the fundamental rate-limiter slowing down a sustainable energy future. Very important problem."

Tesla has been making strides to give EVs a longer travel range through an extensive Supercharger network, as well as its new generation of long-range electric cars that can go up to 400 miles between charges. Musk hopes to make electric cars as convenient and accessible as conventional combustion engine vehicles.
Fast-charging EV batteries are still several years away
StoreDot's five-minute battery will likely not enter the mainstream market for many years, as mass production will not be available for quite some time as the company continues to hone their technology.
StoreDot has experimented with fast-charging batteries in the past for phones, drones, and scooters. In 2014, the company developed a prototype of a charger that could boost your phone's battery from dead to fully-charged in 30 seconds.
