In order to seek more business development methods, SGL expands the role of carbon fiber composite materials in more fields. On April 30, 2019, SGL cooperated with Shanghai Weilai Automobile Co., Ltd. (NIO) to jointly develop a prototype of a carbon fiber reinforced plastic battery case for electric vehicles. The battery case is 40% lighter than traditional aluminum or steel battery cases and has high rigidity And the thermal conductivity is 200 times lower than aluminum, which can better protect the battery body from the external cold and hot. In addition to this, the composite material also imparts excellent airtightness, waterproofness, and corrosion resistance to the battery case.
