StoreDot, the first developer of extreme fast charging battery technology for EVs, announced that its ‘100in5’ EV battery achieved 1,000 extreme fast charging (XFC) cycles without significant cell degradation in its ‘production-ready EV form factor, as per Teslarati.
The 300Wh/kg, 700 Wh/l high energy density cells that achieved a milestone of 1,000 extreme fast charging cycles shipped in pouch format to StoreDot’s global automotive OEM partners for intense real-world testing.
StoreDot has said that the cells were repeatedly charged from 10 to 80 percent capacity in 10 minutes and discharged for one hour before recharging. The ‘100in5’ cell has been in development for years, labeled for its ability to achieve sufficient energy to move 100 miles in just 5 minutes.
Additionally, the cells used in the XFC testing have achieved over 1,000 consecutive cycles before degrading below 80% of the original capacity threshold, said StoreDot in a press release. No visible degradation occurred within the first 600 cycles in which the cells were fast-charged consecutively between 10 to 80 percent.
“The latest tests represent a landmark not just for StoreDot, but also the global battery industry and the entire sustainable mobility ecosystem. Our product performance goal for 2022 was to reach 1000 cycles of consecutive extreme fast charging of 10 to 80 percent in ten minutes, with an energy density of at least 300Wh/Kg.” Yaron Fein, StoreDot’s Vice President of Research and Development, said.
According to Automotive World, this breakthrough follows StoreDot’s announcement in March that it had set a world record of 1200 cycles for its extremely fast charging cells prototype format. StoreDot continues to develop XFC technology in cylindrical and prismatic form factors, with updates expected soon on shipping those to OEM partners.
“I am delighted to announce that not only have we achieved our target but have also exceeded it – and we already have in our labs enhanced formulation that allows us to show further improved performance. This is the first time ever that cell performance of this magnitude has been achieved. The results stand testament to StoreDot’s relentless R&D drive, the enthusiasm of everyone in the company and to the Extreme Fast Charging vision we share with our partners.” Fein added.
While StoreDot achieved its 2022 performance goal by accomplishing the 1,000-cycle threshold without seeing significant degradation, however, the work is not yet finished.
StoreDot focuses on delivering its hype-free technology plan to global automotive companies. This development program goes far into the future, where the target is to provide 100 miles of range within a decade after just 2 minutes of charge.
