General Motors is spending $30m on a US plant to make next generation batteries for its all-electric Chevrolet Volt.

The factory, opening in Michigan in 2010, will assemble lithium ion battery cells manufactured by LG Chem into 400lb packs to power the Volt plug in car and likely other GM models using the same powertrain, newly called ‘Voltec’.

“We chose Chevy because we can’t be niche with the Volt. We have to make it a mass-production vehicle,” Ed Peper, North American vice president of GM’s Chevrolet brand, said at the Automotive News World Congress in Detroit, according to Reuters.
