Ford Motor Co. will employ Compact Power Inc. as their main battery supplier. Does CPI sound familiar? It should  - it created the lithium-ion battery pack used in Chevrolet's Volt.

The battery maker is a subsidiary of popular electronics producer LG. LG is probably best known in the United States and Canada as a maker of batteries and entertainment devices, such as cell phones and televisions.

"CPI is an emerging leader in the lithium-ion battery field, and we are pleased to have them as a strategic supplier as we prepare to bring the Ford Focus Electric to market," said Sherif Marakby, Ford director of Sustainable Mobility Products and Hybrid programs.

"We are moving aggressively with our electrification strategy and our work to help make Michigan a center of excellence for a range of electrified vehicles."

Assembly of battery packs for the Focus Electric will begin next year. Compact Power is still finalizing the U.S. site to put the battery packs together for the Focus.

The Focus Electric, with a range of 100 miles, is to begin production next year at the Michigan Assembly Plant in Wayne. The gasoline version of the all-new 2011 Focus begins assembly later this year in the plant, which has gotten a $550 million makeover.
