Electric vehicle battery manufacturer A123, which received a $249 million stimulus grant from the Department of Energy, filed for Chapter 11 bankruptcy protection October 15 in the U.S. Bankruptcy Court for the District of Delaware to facilitate an agreement in which Johnson Controls will purchase its automotive business assets for $125 million. The company has drawn down roughly $131 million of its grant, and has faced problems with batteries supplied to Fisker as well as low demand for electric vehicles. The previous day, the company announced that it could default on some debt agreements and that it was considering strategic alternatives.
