Japanese electronics firm Toshiba has launched a new lithium-ion battery featuring an aluminum baseplate that dissipates approximately twice the heat of current modules.

The new SCiB battery is now available in Japan and internationally.

Aluminum has a lower thermal resistance than the resin materials typically used in baseplates. As it is a conductor, the baseplate must be insulated from the battery cells. Toshiba has developed a structure that achieves the required voltage resistance. When used with the same cooling system normally applied by customers, and under typical operating conditions, the heat dissipation performance extends battery life.

Demand is growing for batteries that can support constant rapid charging and discharging in applications ranging from electric buses to power load leveling in stationary applications, but constant input and output at high power levels in a short time generates life-shortening heat in the batteries. The challenge for battery developers is to manage heat dissipation and maintain battery life while delivering high power input and output in a short time.

Toshiba’s SCiB rechargeable batteries have a lithium titanate negative electrode that delivers safe operation, a long life, low temperature performance, fast charging, high input and output, and a wide effective state of charge (SOC), according to the company. They are widely used in hybrid vehicles and industrial applications, including electric buses, cranes, trains and automated guided vehicles in logistics centers.

In addition to battery packs and cells, Toshiba also offers battery modules that can be connected in series or in parallel connections to meet required voltages and capacities.
