General Motors and Honda are looking to supercharge development of zero-emission vehicles.
The two companies have struck an agreement that will see the American and Japanese automakers collaborate on the development on the next-generation of battery technology.
Both companies will be aiming to create a battery that has a higher energy density and is smaller and quicker to charge than current batteries and to accelerate each company's electric car plans.
GM is set to build the battery systems which Honda would then source from the US carmaker. The joint venture will help lower the cost of electric vehicles for each manufacturer making it more likely that mass-produced electric cars can be brought to market sooner rather than later.
"This new, multi-year agreement with Honda further demonstrates General Motors' capability to innovate toward a profitable electric portfolio," said Mark Reuss, GM executive vice president of global product development.
"GM's decades of electrification experience and strategic EV investments, alongside Honda's commitment to advancing mobility, will result in better solutions for our customers and progress on our zero emissions vision."
The two companies will also work together to develop hydrogen fuel cell technologies and vehicles by 2020. Honda was one of the first manufacturers to build a production version of a fuel cell vehicle with its Clarity in 2008.
General Motors produced the first modern electric in the mid-1990s, the GM EV1 (above), while Honda has previously sold hybrid vehicles like the Insight but no fully-electric cars yet. It has confirmed it will enter the segment with a production version of its Urban EV concept first displayed at last year's Frankfurt motor show (below).
