StoreDot announced today that its “100in5” EV battery has achieved 1,000 extreme fast charging (XFC) cycles without significant cell degradation in its “production ready EV form factor.”

The “100in5” cell, named for its ability to achieve enough energy to travel 100 miles in just 5 minutes of charging, has been in development for several years. StoreDot has shipped the pouch-format EV battery to OEM partners globally for real-world testing.

The 300Wh/kg, 700 Wh/l high energy density cells achieved a new landmark milestone of 1,000 extreme fast charging cycles without significant degradation. StoreDot says the cells were repeatedly charged from 10 to 80 percent capacity in just ten minutes and were then discharged for one hour before recharging. The cells used in the XFC testing achieved over 1,000 cycles consecutively before degrading below 80 percent of the original capacity threshold, StoreDot said in a press release. No noticeable degradation occurred before the first 600 charging cycles were completed, even though the batteries were fast-charged between 10 to 80 percent.

StoreDot’s Vice President of Research and Development, Yaron Fein, said:

“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.”

StoreDot accomplished its 2022 performance goal by achieving the 1,000-cycle threshold without seeing significant degradation. The work is not finished, however.

Fein went on to state that while he was delighted that the target was reached, StoreDot has already exceeded it. “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.

StoreDot plans to begin mass production of the “100in5” cell by 2024, with the capability to accumulate at least 100 miles of range after just 5 minutes of charging.
