Store Dot, a company that specializes in high-speed recharging, has built a first-generation lithium-ion battery that can Charging an electric car More quickly than needed to fill up 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 main investors, the German car manufacturer.DaimlerBritish oil company, British Petroleum, and electronics giants Samsung and TDK.
Before collaborating with these investors, in 2012 the Store Dot founder tested the battery on phones, drones and scooters.
Eric Esperance, analyst at consulting firm Roland Berger, believes that super-fast charging will be a “revolution” but that there are additional milestones to be completed.
“We are still far from the industrial vehicle market,” he told AFP.
In 2019, the Nobel Prize in Chemistry was awarded to 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.”
Mersdorf notes that “charging speed was not part” of the original design that won the Nobel Prize, 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.
Store dot chemists who used to wear goggles and white coats collect 100 batteries a week and send them to companies to use in their products.
A society free of fossil fuels
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.
And with the increasing awareness of the public opinion of the importance of addressing a crisis Climate change, Manufacturers are turning their focus towards producing less polluting cars, but the road is long.
On the ground, charging stations must be adapted to accommodate new generation batteries, which cost between $ 1,500 and $ 10,000 depending on capacity.
According to the International Energy Agency, global sales of electric cars reached 2.6% in 2019, especially because of their exorbitant price.
Mersdorf is hoping that the world will accelerate the transition to electric vehicles more widely, as this has a “tremendous impact on the planet”.
Despite the advantages of using lithium-ion batteries, recycling them remains a problem facing manufacturers, as they have a life span of between 3,000 and 3,500 charges, according to Esperance.
“We have to create a recycling system as is the case with lead-acid batteries. Currently, this network is being created,” he says.
