Mass production of solid state batteries, the much-awaited breakthrough development to unlock energy density and rapid charging improvements, are still at least a decade away accoring to StoreDot, a pioneer of extreme fast charging battery technology for electric vehicles. The company is urging global automotive manufacturers to consider interim technologies such as semi-solid batteries.
Solid-state batteries have a plethora of advantages for the electric vehicle market, providing cost-effective fast and safe charging batteries with high energy densities, however, they are still a work in progress, says the company, and face significant challenges before they can be mass-produced at scale. Solid electrolytes are used in solid-state batteries rather than liquid or polymer gel electrolytes found in current technologies, such as lithium-ion or lithium polymer batteries.
“It’s crucial 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.” said Dr Doron Myersdorf, StoreDot CEO.
“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.”
