StoreDot achieves target of 1,200 cycles for its fast charging cells

by Nilesh Wadhwa 24 Mar 2022

Israel-based energy company, StoreDot said it has passed a major milestone of being the world's first company to test silicon dominant cells for more than 1,000 cycles.

Just few days ago, the company received a strategic investment from Ola Electric which gives it access to the Indians company’s XFC battery technology and also exclusive rights to manufacture batteries integrating StoreDot’s fast charge technology in India.

Using a specially-designed testing form factor, the company claims it has now exceeded 1,200 cycles with cells that are taken to 80 percent of charge in 15 minutes, and then discharged for one hour. The results was achieved with a high energy density of 300Wh/kg and 680 Wh/l in real-world conditions at room temperature.

StoreDot is now beginning to advance to B-samples, using larger form factors, to ship to global automotive manufacturers later this year for testing in future electric vehicles.

Yaron Fein, VP – R&D, StoreDot said, "The 1,200 consecutive cycles of extreme fast charging is a critical milestone that would have been unimaginable just two years ago. This reaffirms our roadmap of delivering '100-in-5' cells for global automotive manufacturers within two years and creating batteries that will transform the experience of electric vehicle drivers by eradicating their charging and range anxieties."

When a lithium battery is charged and discharged once, it is called a cycle. The lithium battery capacity degrades as the cycle number increases. Battery cycle life is measured in cycles, with an industry standard of cycles to 80 percent capacity often used as a benchmark and so creating cells that can charge for 1,200 cycles whilst maintaining the industry standard is a significant achievement.

StoreDot’s development program aims to deliver 100 miles after just 2-minutes of charge within a decade. Its extreme fast charging cells will be available in both pouch and the 4680 family form factor.
