StoreDot has shipped extreme fast charging battery cells capable of more than 1,000 consecutive cycles to its global automotive OEM partners for intense real-world testing. The pouch format cells offer a high energy density of 300Wh/kg and 700 Wh/l.
Most importantly, the cells exhibit the company’s ‘100in5’ EV performance, allowing drivers to add 100 miles of range for each 5 minutes of charging.
The cells were repeatedly charged from 10 to 80% capacity in 10 minutes and then discharged for one hour before recharging, the company said. The EV cells achieved over 1,000 of these extreme charging cycles consecutively before degrading below the 80% of the original capacity threshold. No noticeable degradation occurred within the first 600 cycles in which the cells were consecutively fast charged between 10 to 80%.
The company said it's in the process of developing the XFC technology in both cylindrical and prismatic form factors with updates expected soon on shipping those to OEM partners.
“The latest tests represent a landmark not just for StoreDot, but also the global battery industry and the entire sustainable mobility ecosystem,” said Yaron Fein, StoreDot Vice President R&D.
Explaining, the VP said when a lithium battery is charged and discharged once, it is called a cycle, and typically lithium battery capacity degrades quickly in fast charging cycles.
The company said it remains focused on delivering its hype-free technology roadmap to global automotive companies. This relentless development program extends far into the future, where the target is to deliver 100 miles of range after just 2 minutes of charge within a decade, it said.
