Why Battery Cost Could Put the Brakes on Electric Car Sales – Bloomberg

29 Nov 2017   Electric Cars

Battery prices need to drop by more than half before electric vehicles will be competitive with cars powered by internal-combustion engines, according to Bloomberg New Energy Finance, whose two-day Future of Energy summit in Shanghai concludes on Wednesday. That’s likely to happen by 2026, when the cost for lithium-ion battery packs is projected to fall to about $100 per kilowatt hour, speakers at the summit said.

The Tech Race

The focus of the industry has moved from lithium-ion batteries using liquid electrolytes to solid-state ones, which address the need for safer and more powerful energy storage. Toyota Motor Corp. has said it’s working to commercialize the technology in the early 2020s, and Dyson Ltd. says it will build an electric car using solid-state batteries in three years. The British company plans to invest one billion pounds ($1.3 billion) to develop the car, plus the same sum to create solid-state batteries for it. That investment would outpace those made by other major EV makers such as Tesla Inc.

Major Players

Panasonic Corp. of Japan, BYD Co. of China and South Korea’s LG Chem Ltd. are the top manufacturers of lithium-ion batteries for EVs, according to BNEF. Shares in companies such as lithium-salt maker Stella Chemifa Corp. and Sociedad Quimica y Minera de Chile SA, which mines chemicals including lithium, are on the rise.

As demand rises for metals used in batteries, beneficiaries include companies such as Japan’s Tanaka Chemical Corp., which manufactures and sells components for the storage devices.
