Israeli battery maker Storedot said its silicon-dominant extreme fast charging battery cells successfully passed extended charging tests without degradation.
The company claimed results showed consecutive extreme fast charging conditions did not degrade cells, even after 1,000 consecutive extreme fast charging cycles.
It said it ran full cycle charge tests, emulating real-world use case. Extreme fast charging was applied from 10–80% of the charge in 10 minutes. The remainder of the charging cycle, from 0–10% and 80–100% was done with slower 1C charging.
The silicon battery cells were also tested for full slow charging cycles from 0–100%, and achieved a similar cycle life performance, it claimed.
Despite each cycle applying extreme fast charging for most of the charge (i.e. 70%), the cells showed no additional degradation, the company said. The result is on a par with cells slow charged from 0–100%.
Dr Doron Myersdorf, StoreDot CEO, said: “The significance of testing our silicon-batteries under various use-case conditions demonstrates our battery’s robustness regardless of drivers’ charging habits, recharging frequency, or charger power.”
The company said it remains on target for mass production readiness of “100in5” cells next year delivering at least 100 miles of range in five minutes of charging.
