CATL has begun mass production of a new high-capacity lithium-ion battery, called Qilin in Chinese, and will initially ship it to Geely’s electric vehicle brand Zeekr. The company’s 009 vans equipped with the batteries will be available to customers in the second quarter. Financial media outlet Caixin first reported on the collaboration, citing a Zeekr representative. According to the Chinese battery giant, the Qilin battery has an energy density of 255 watt-hours per kilogram and can deliver 13% more power than Tesla’s 4680 batteries in the same volume, resulting in a driving range of 1,000 kilometers (621 miles).
