Toshiba Corporation has launched a new SCiB module, a lithium-ion battery designed for use in EV buses, electric ships and stationary applications. The system features an aluminum baseplate that is stated to dissipate approximately twice the heat of current modules. It will be available from mid-April 2025, in Japan and internationally.
Toshiba notes that the use of lithium-ion batteries is increasing and diversifying, and that there is a growing demand for batteries that can support constant rapid charging and discharging in applications as diverse as electric buses and power load leveling in stationary applications.
The Toshiba’s SCiB rechargeable batteries have a lithium titanate negative electrode that realizes safe operation, a long life, low temperature performance, fast charging, high input and output, and a wide effective state of charge – attributes increasingly in demand.
Toshiba says this new module is the first to feature an aluminum baseplate, which is an excellent conductor, and dissipates heat at approximately twice the rate of current battery modules when used with conventional cooling systems.
Aluminum has a lower the thermal resistance than the resin materials usually used in baseplates. However, as a conductor, the baseplate must be insulated from the battery cells. Toshiba says it has developed a novel structure that achieves the required voltage resistance, which enables commercialization.
