Super-fast charging experts at StoreDot recently announced a first-generation lithium-ion battery with no more than how long it takes to refill a gas tank in conventional cars. .
” We’re going to change the whole driver’s experience, the worry about the road … that you can get stuck on the highway when the car runs out of electricity, ” said StoreDot founder Doron Myersdorf. .
This innovation could put an end to hours waiting to charge an electric car, he continued.
Hundreds of prototypes have been tested by this manufacturer. Myersdorf-based company, based in Herzliya, near Tel Aviv, is backed by four main investors: German car maker Daimler, British Petroleum, and electronics giants Samsung and TDK.
Myersdorf, who founded StoreDot in 2012, tested the battery on a variety of phones, drones, and scooters, before moving on to “large toys” for electric cars.
But Eric Esperance, an analyst at the consulting firm Roland Berger, warns that while super-fast charging will be “revolutionary”, there are still phases to be clear.
” We are still quite far from the industrial car market ” – he said.
In 2019, the Nobel Prize in Chemistry was awarded to John Goodenough (USA), Stanley Whittingham (UK) and Akira Yoshino (Japan) for inventing the lithium-ion battery.
” The ultra-light, fast-charging and powerful batteries are now used in everything from phones to laptops and self-driving vehicles, ” says Goodenough.
Myersdorf said charging speed was not part of the original Nobel Prize-winning design, so he studied what was ” considered impossible “: a lithium-ion battery that can be charged in several ways. minute.
” We want to show that you can take a lithium-ion battery, replace some of its material, and then fully charge it in 5 minutes, ” he said.
This engineer replaced the original graphite material in the battery’s negative anode with silicon.
” We took that amazing advanced lithium-ion battery material and upgraded it for super-fast charging. ”
These batteries will be assembled in a laboratory equipped with large, sealed glass boxes to prevent oxygen from leaking inside.
StoreDot chemists can make up to 100 batteries a week, and then ship them to other companies wishing to use them in their products.
A society without fossil fuels
The team has now embarked on the development of the second generation of batteries to cut costs.
Although the design cycle of a car is typically four to five years, StoreDot hopes to be able to speed up the process.
” We are working to bring this solution to multiple markets at the same time by designing manufacturing plants capable of mass-producing these batteries ” – Myersdorf said.
The Nobel Prize Panel praised lithium-ion batteries for their ” enormous storage of solar and wind energy, contributing to a fossil fuel-free society “. And as communities increasingly prioritize solutions to climate change, manufacturers are also gradually shifting towards the production of less polluting vehicles.
But there is still a long way to go.
Scientists at StoreDot are making batteries in closed chambers
First of all, the charging stations must be modified to accommodate the new generation batteries, which cost between $ 1,500 and $ 10,000 depending on capacity. Electric cars are still quite expensive too, and in 2019 they will only account for 2.6% of all cars sold globally.
For Myersdorf, the sooner the world will switch to electric vehicles, the better, as that would have a ” huge impact on the planet” . But lithium-ion battery recycling is still a problem, as lithium-ion batteries have a lifespan of 3,000 to 3,500 charges, Esperance said.
” We have to set up a recycling system, like the currently established lead-acid battery recycling system. ”
Both extracting and recycling lithium present the ecological, political, and economic challenges that technology must overcome.
