Toyota Motor and Panasonic said on Wednesday they were considering jointly developing batteries for electric vehicles (EVs), a partnership that could help Panasonic extend its market lead in automotive lithium-ion batteries.

The announcement builds on an existing agreement under which Panasonic manufactures batteries for Toyota’s petrol-electric and plug-in hybrid vehicles.

Toyota said last year it was planning to add fully electric vehicles to its product line-up in a shift away from its previous green-car strategy of focusing on plug-in hybrid and fuel-cell vehicles. It has said it plans to start marketing pure EVs in the early 2020s.

Panasonic is the main EV battery supplier for luxury US car-maker Tesla. The electronics firm commands 29 per cent of the market for batteries used in plug-in hybrids and EVs, according to Nomura Research data for the first half of 2017.


Nearest rival LG Chem Ltd holds 13 per cent of the market, followed by China's BYD Co Ltd on 10 per cent and Contemporary Amperex Technology at 9 per cent.

Economies of scale

"Working with automakers from the initial stages could allow battery makers to win orders that unlock economies of scale further down the road," Credit Suisse analyst Mika Nishimura said in a research note to clients ahead of the Toyota-Panasonic announcement. "Partnerships could also allow battery makers to share R&D and capex costs with automakers to some extent."

Panasonic sees batteries as central to its plan to nearly double automotive business revenue to 2.5 trillion yen by the year through March 2022. To that end it has been expanding battery production capacity globally.

It started mass production of battery cells at Tesla’s “Gigafactory” in the US state of Nevada earlier this year, and plans to follow suit at a new plant in Dalian, China. It is also adding new production lines in Japan. – Reuters
