Hitachi Delivers High Output Prismatic Li-ion Battery Cell

Hitachi Automotive Systems today announced that the company will be supplying 5,000W/kg high output power density prismatic lithium-ion battery cells for the new model Chevrolet Malibu Hybrid to be sold by General Motors (GM) in 2016.

These prismatic lithium-ion battery cells being delivered for the 2016 new model Chevrolet Malibu Hybrid employ heat resistant separators to ensure the ionic conductivity between the positive and negative electrodes, achieving not only a high output power density of 5,000W/kg, but also a high level of safety. In addition to this, the battery's ability to maintain its high output power density in GM evaluations, even under extremely low temperatures such as the minus 30℃ cold region test, led to its adoption.

Hitachi's lithium-ion battery operations for vehicles began in 1999. To date, a total of over 5 million lithium-ion batteries have been introduced into the market for commercial hybrid buses and trucks, as well as hybrid passenger cars.
