Honda joins the quest for solid-state EV batteries

Tighter global emissions regulations are forcing automakers worldwide to shift to electric cars, including all-battery EVs that will require capacity to deliver longer ranges and faster charge times, but at lower cost than lithium-ion batteries.

"We've been researching all solid-state batteries," Honda spokesman Teruhiko Tatebe said. "At the moment, we're not developing them with another automaker."

Kyodo News reported on Thursday that Honda and Nissan were developing all solid-state EV batteries. Nissan was not immediately available for comment.

A growing number of automakers including Toyota and Volkswagen and smaller innovator Fisker are developing all solid-state batteries, which offer more capacity and better safety than conventional lithium-ion batteries by replacing their liquid electrolyte with a solid, conductive material.

Just this week, Colorado tech company Solid Power said it was partnering with BMW on the technology. And earlier this month, Toyota said it was considering jointly developing the batteries with Panasonic to share high R&D costs.

The automaker is planning to have a production-ready battery in the early 2020s, and has highlighted the need to accelerate the pace of battery development as it and other automakers plan to ramp up the number of electric models they sell in the coming decades.
