Israeli battery developer StoreDot has reported progress in the stability of its fast-charging silicon-dominated battery cells. The company says it has exceeded 1,200 cycles with cells charged to 80 per cent in 15 minutes and then discharged for one hour.
StoreDot says that these results were achieved with an energy density of 300 Wh/kg and 680 Wh/l, respectively, under real conditions at room temperature and without additional pressure. StroeDot is now starting to develop B-samples with larger form factors that will be delivered to automotive manufacturers later this year for testing in future electric vehicles. The company says that it remains on track for the mass production of ‘100in5’ cells by 2024 – which it says are capable of achieving 100 miles of range (161 kilometres) in just five minutes.
Yaron Fein, StoreDot Vice President R&D says: “I’m hugely proud of our recent achievement. 1200 consecutive cycles of extreme fast charging is a critical milestone that would have been unimaginable just two years ago.” He says that this “…reaffirms our roadmap of delivering ‘100in5’ 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.”
StoreDot aims to make its fast charging cells available in both pouch and the 4680 family form factor. The company has high goals: the target is to deliver 100 miles of range after just two minutes of charge within a decade. This goal was revealed earlier this month when the Israeli battery developer presented its strategic technology roadmap ‘100inX”.
Just a few days ago, we reported that India’s Ola Electric has invested in Israel’s StoreDot to access the latter’s fast-charging technology. Ola says this was the first of several global investments as it looks to ramp up its R&D in advanced cell chemistry and manufacturing.
In 2024, StoreDot wants to bring the battery cells it is currently developing into series production with the Chinese battery manufacturer EVE Energy.
