China Reminds Battery Makers to Avoid Excess Capacity Growth

China summoned the country’s leading battery makers for a second time in a little over three months, reinforcing a call to restrict capacity expansion and avoid the price wars that have damaged other renewable-energy industries in the past.

Several government agencies, including the Ministry of Industry and Information Technology, called on 16 manufacturers of electric-vehicle and stationary batteries to step up efforts to improve product quality and safeguard intellectual property, as well as controlling growth.
