StoreDot, an Israel-based electric vehicle extreme fast charging (XFC) battery startup, today announced that it has advanced technology that extends the life span of batteries, making them highly effective not only during the vehicle life span, but also for second-life applications.
The technology combines the electrochemistry system of the company’s silicon dominant cells to ensure that there is minimal drop-off in performance even as the battery ages.
StoreDot reports that a robust performance is maintained even after 1,000 cycles and 80% capacity, the point at which rival lithium-ion fast-charging technologies start to rapidly deteriorate in performance. Even after 1,700 cycles, long after the accepted industry norm, StoreDot claims its batteries can maintain 70% of their original capacity, making them effective in second-life usage for less dynamic applications such as in energy storage and grid load balancing systems.
Dr. Doron Myersdorf, StoreDot CEO, said:
StoreDot is well known for creating extreme fast charging technologies and helping drivers overcome charging anxiety, which is currently the biggest barrier to EV ownership.
But we believe in advancing the entire battery eco-system, ultimately delivering an optimum solution to sustain the transition to full EV electrification. This latest development is proof of that.
We now have the ability to hugely extend the life of our batteries, long after their vehicle service life. This not only has benefits for the drivers of EVs, allowing them to maintain performance of their vehicles for many more years, but also in second-life applications.
Not only will this transformative development encourage more people to drive EVs, but this technology has huge benefits for sustainability, too, reducing the need to retire and recycle an expensive component that can now serve in critical second-life applications.
StoreDot says it’s in advanced talks with global car makers. It also says it’s on track to deliver mass-produced XFC batteries, which provide a 50% reduction in charging time at the same cost, by 2024.
In early September 2021, StoreDot announced that it produced the first 4680 cylindrical cell, that it claims can charge in only 10 minutes.
In November, StoreDot claimed it had become the first company to produce XFC cells for electric vehicles on a mass production line. And on December 1, 2021, StoreDot announced new patented technology that uses a background repair mechanism to allow battery cells to regenerate while they are in use.
