Key innovations claimed by Toshiba for its new 20Ah-HP SCiB rechargeable lithium-ion battery cell are heat-generation control, long life and compatibility. The amount of heat generated through battery usage or charging has been reduced, the company says, whilst simultaneously extending the lifespan in the same 20Ah form factor.

This makes it a good candidate for situations where battery cells must suppress heat and operate continuously, such as during the rapid charging of commercial vehicles, regenerative power systems for rolling stock, and industrial equipment. Suitable use cases include electric vehicles, logistics and other types of transport such as hybrid electric trucks.

Toshiba observed that the market is increasingly demanding batteries that deliver both high-energy and high-power characteristics. This has required a trade-off for rechargeable lithium-ion batteries. In an EV, for example, a high-energy battery allows the vehicle to drive further...
