An Israeli tech startup has developed a battery for electric vehicles that can be charged within five minutes, in a move aimed at encouraging the use of environmentally friendly cars and dispelling consumers’ concerns about the limited autonomy of these vehicles.
The “Store Dot” company, which specializes in high-speed recharging, has created a first-generation lithium-ion battery that can charge an electric car faster than that required to fill the tank of a regular car with fuel.”We are changing the driving experience” by solving the problem of “(electric) vehicle charging interruption on the highway,” says StoreDot founder Doron Mearsdorf.
Mersdorf believes that the new technology could save the driver the hassle of waiting hours to recharge an electric car battery.
The startup is currently testing hundreds of models of these batteries.
Store Dot, which is headquartered in Herzliya, near Tel Aviv, has the support of four major investors: German car manufacturer Daimler, British oil company British Petroleum, and electronics giants Samsung and TDK.
In 2019, the Nobel Prize in Chemistry was awarded to American John Godinav, Britain’s Stanley Whitingham and Japanese Akira Yoshino for inventing lithium-ion batteries.
At the awards ceremony, the Royal Swedish Academy of Sciences said, “This powerful, lightweight and rechargeable battery has been used in everything from mobile phones to laptops and electric cars.”
Mearsdorf notes that “charging speed was not part” of the original Nobel Prize winning design, so he and his team worked on “what was considered impossible: a lithium-ion battery can be fully charged within minutes.”
“We wanted to prove that it is possible to take the lithium-ion battery, replace some of its components, and then charge it within five minutes,” he adds.
The engineer replaced the conductive part of the battery’s negative electrical medium with silicon.
“We take this amazing innovation from the Li-ion battery and then the lithium battery and develop it to achieve ultra-fast charging capability,” he says.
The batteries are collected in a laboratory equipped with large sealed glass boxes to prevent oxygen penetration.
The company’s team is working on a second generation of batteries to keep costs down. And although the vehicle design cycle “typically takes four to five years”, they are looking to speed up the process.
“We are working to bring this solution to the market by designing manufacturing facilities that will be able to mass produce this battery,” says Store Dot founder.
On the ground, charging stations must be adapted to accommodate new generation batteries, which cost between $ 1,500 and $ 10,000 depending on capacity.
