DETROIT -- General Motors Co., eager to develop electric vehicles more quickly, is partnering with its battery cell supplier, South Korea's LG Group.
An agreement signed last week will "help GM expand the number and types of electric vehicles it makes and sells," GM said in a statement.
The pact broadens opportunities for LG, which supplies battery cells for the Chevrolet Volt and Opel/Vauxhall Ampera plug-in hybrids. The Ampera and Volt debut in Europe in November.
The Volt's success prompted GM and LG to collaborate further on vehicle electrification, leading to a formal alliance, GM said.
Last year, for example, the two companies worked together to develop a demonstration fleet of electric Chevrolet Cruze compacts, which were used as official vehicles during the G20 summit in Seoul. GM now is market testing those vehicles.
GM and LG engineers will work together on development of electric vehicle platforms and components, GM said. Vehicles born out of the partnership "will be sold in many countries," GM said.
GM CEO Dan Akerson has vowed to stay ahead of the competition on vehicle electrification. He is pressing his team to reduce the cost of the Volt, partly through economies of scale by applying the technology across more GM vehicles.
This month, GM said the Volt powertrain will be put on an upcoming Cadillac sedan.
