ou need a score card these days to keep up with what company is supplying battery cells to Tesla and the company doesn’t help much by keeping such information close to its proverbial vest. We do know that at the present time, Panasonic, CATL, and LG Chem are supplying battery cells to Tesla. We also know that Tesla is planning to manufacture some battery cells itself.
On December 1, Reuters reported that South Korea’s LG Chem will double its battery cell production capacity in China to meet Tesla’s needs in that country. LG Chem battery cells are currently used in Model 3 cars built at the Shanghai factory.
