Hitachi Improves EV Batteries

Hitachi is now up to the 4th generation of its lithium ion batteries. They are claimed to be 50% more powerful than the current version, and will be shipping samples to automakers this fall for evaluation. The company hopes to have them in mass production circa 2013.

Earlier this year GM ordered 100,000 battery packs from Hitachi for hybrid vehicles.
