General Motors (GM) announced on August 11 that it has awarded a production contract to A123 Systems for batteries to be used in future GM electric vehicles (EV) that will be sold in global markets. A123, which operates a battery laboratory in Warren, Michigan, is a Massachusetts-based developer and manufacturer of advanced lithium ion batteries and systems. The contract includes advanced cells and fully integrated electronic components. The specific vehicles and brands will be announced later.

In preparation for production, teams from GM and A123 will work on developing calibrations and software controls for the battery system. The carmaker has said it is committed to offering a full line of electric vehicles and that each vehicle line calls for a different battery specification. GM and A123 are already working on next-generation lithium ion batteries. Also this week, the battery manufacturer was awarded $2,992,744 by DOE to develop and demonstrate dry-process electrode fabrication to reduce the cost of EVs. The award is part of DOE's $175 million support for advanced vehicle technologies. See the GM press release and the separate DOE advanced vehicles press release.
