Toshiba's new fast-charging battery could triple the range of electric vehicles

9th Oct 2017

"...Toshiba's SCiB (Super Charge ion Battery) has been around in various forms since 2007, with its chief claim to fame an ability to charge to 90 percent of capacity in just five minutes. It also boasts a life-span of 10 years and high levels of safety, and has found its way into a number of notable EVs, including Mitsubishi's i MiEV and Honda's Fit EV.

The current SCiB uses lithium titanium oxide as its anode, but Toshiba says it has now come up with a better way of doing things. The next-generation SCiB uses a new material for the anode called titanium niobium oxide, which Toshiba was able to arrange into a crystal structure that can store lithium ions more efficiently. So much so, that the energy density has been doubled.

Toshiba has tested out a 50-Ah version of the new battery and reckon that it too boasts excellent safety and a long life cycle, retaining more than 90 percent of its capacity after 5,000 charge cycles. It says that if incorporated into a compact EV, it would allow for a range of 320 km (186 mi) after just a six minutes of ultra-rapid charging, which is around three times the range offered by a standard, similarly charged lithium-ion battery. ..."
