The pair is already working together on fuel-cell technology

General Motors and Honda have announced a partnership to develop advanced battery components, in an attempt to speed up the rollout of electric cars that are attractive to consumers.

The agreement will see the two companies collaborate on development of GM's next-generation battery systems, with Honda to source its battery modules from the American giant.

According to Honda, the 'combined scale and global manufacturing efficiencies' created by the partnership will help lower the cost of production, delivering savings to the companies involved and end customers.

This isn't the first time GM and Honda have paired up to develop alternative powertrain technology. The two are already working to developed an advanced hydrogen fuel-cell system by 2020, and are pushing to nail down a commercial hydrogen fuel storage system.

"This new, multiyear agreement with Honda further demonstrates General Motors’ capability to innovate toward a profitable electric portfolio,” said Mark Reuss, General Motors 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.”

Both brands are gearing up to release electrified mass-market vehicles in the coming years: Honda in the form of the Urban EV, previewed with a cutesy concept car in Frankfurt last year, and GM in the form of 20 electric vehicles by 2023.

Mark Reuss, the aforementioned GM executive, said the group's electric vehicles will learn from the Bolt EV. China will drive the push into electrification, but the rollout of plug-in GM vehicles will be global.
