Toshiba claim their new version of the SCIB cell can be 90% recharged in 6 mins ..( 9C charge rate ?) with no detrimental effect
. "We are very excited by the potential of the new titanium niobium oxide anode and the next-generation SCiBTM,” said Dr. Osamu Hori, Director of Corporate Research & Development Center at Toshiba Corporation. “Rather than an incremental improvement, this is a game changing advance that will make a significant difference to the range and performance of EV. We will continue to improve the battery’s performance and aim to put the next-generation SCiBTM into practical application in fiscal year 2019.”
Rigorous testing of a 50Ah prototype of the new battery has confirmed tihat it retains the long life cycle, low-temperature operation, excellent safety and rapid recharging characteristics of the current SCiBTM. The energy density by volume of battery is twice that of the current SCiBTM. The next-generation SCiBTM maintains over 90% of its initial capacity after being put through 5,000 charge/discharge cycles, and ultra-rapid recharging can be done in cold conditions, with temperatures as low as minus 10°C, in only ten minutes.
Toshiba will continue to develop higher energy density batteries that extend the range of EVs and support ultra-rapid recharging, and aims to commercialize the next-generation SCiBTM in fiscal year 2019.
