Tesla Motors Inc. said Wednesday it has started the “mass production” of lithium-ion battery cells at the company’s battery factory outside Reno, Nev., alongside partner Panasonic Corp.
The cells will be used in Tesla’s energy-storage products and at a later date in the Model 3, the mass-market, all-electric sedan Tesla plans to start selling by the end of this year. The car is a crucial step in Tesla’s expansion plans.
