Extreme fast charging EV battery specialist StoreDot says mass-produced solid state batteries are still at least a decade from mass production and that automotive manufacturers should be considering semi-solid batteries in the interim.
Solid-state-batteries are cost-effective fast and safe charging batteries, with high energy densities, however, according to the company, they remain a work in progress, and still face significant challenges before they can be manufactured at scale.
A solid-state battery uses solid electrodes instead of the liquid or polymer gel electrolytes found in current technologies such as lithium-ion or lithium polymer batteries.
StoreDot’s extreme fast charging battery cells are now being shipped in pouch format to its global automotive OEM partners for intense real-world testing.
The company says these allow drivers to charge consecutively 100 miles of range for each five minutes of charging.
Dr Doron Myersdorf, CEO at StoreDot said, “It’s crucial that leading battery developers like StoreDot give global automotive manufacturers a realistic and hype-free roadmap for the introduction of extreme fast-charging battery technologies.
“Right now, despite some of the bullish claims by our rivals, all-solid-state batteries are still at least 10 years away.
“They are certainly no silver bullet for any vehicle maker currently developing fast charging electric vehicle architectures.
“We believe a more practical step is the introduction of semi-solid-state batteries which we are targeting for mass production by 2028.
“These will be advanced, safe, high performing cells that can achieve 100 miles of charge in just three minutes.
“They have the additional benefit of requiring a simpler and less challenging manufacturing process than all-solid-state technologies.”
