Automakers work together on next-generation batteries

Headline Goes Here

ORLANDO, Fla. - Toyota Motor Corp. and BMW Group said on Thursday that the companies will start joint research to develop a new lithium-air battery, called "lithium-air," for green vehicles.  The next-generation battery will be more powerful than the current lithium-ion batteries used in electric vehicles.

BMW AG board member Herbert Diess told reporters that  the collaboration with the Japanese automaker will help both companies boost competitiveness in new technologies.

The automakers said they are aiming to complete a fuel-cell vehicle system by 2020, and a concept for a mid-size sports vehicle by the end of this year.  They will also work together on developing lightweight technologies such as composites, which will help make cars greener.
