Storedot claims EV battery life breakthrough

Battery specialist StoreDot, which specializes in fast battery charging, has unveiled technology that it claims will significantly extend the life of batteries for electric vehicles (EVs).

The Israeli firmwhose flagship XFC battery technology is said to deliver a 50 percent reduction in charge time, claims this latest innovation will extend the life of EV batteries, reducing their environmental impact and allowing drivers to maintain the performance of their vehicles for many years to come without affect the range.

According to a statement from the company, the improved technology combines the innovative electrochemical system of its silicon-dominant cells to ensure that there is minimal performance degradation even as the battery ages beyond its useful EV life.

It claims the technology allows batteries to maintain robust performance beyond 1000 cycles and 80% capacity, the point at which competing lithium-ion fast-charging technologies begin to rapidly deteriorate in performance. Even after 1700 cycles, long past the accepted industry standard, StoreDot’s batteries would retain as much as 70% of their original capacity. This makes them potentially effective for second-life use in applications such as energy storage and grid load balancing.

Doron Myersdorf on the EV battery of the future

The technology also works in conjunction with StoreDot’s recently announced self-healing cell system, which identifies underperforming cells in the electric vehicle and takes them out of service for unobtrusive repair.

StoreDot CEO Dr. Doron Myersdorf said: “StoreDot is known for creating extremely fast charging technologies and helping drivers overcome the fear of charging, which is currently the biggest barrier to owning an EV. …..We now have the opportunity to extend the life of an EV. greatly extending our batteries well beyond their vehicle life, benefiting not only EV drivers, allowing them to maintain the performance of their vehicles for many years to come, but also for second-life applications.

The company – whose strategic investors include BP, Daimler, Samsung Ventures and TDK – is said to be in advanced talks with leading global automakers and remains on track to deliver mass-produced XFC batteries by 2024.
