TOKYO—Panasonic Corp. said on Monday it will begin mass production of a new lithium-ion battery for Tesla Inc. before the end of March 2024 at a plant in Japan.
Unveiled by the Japanese company in October, the 4680 format (46 millimetres wide and 80 millimetres tall) battery is around five times bigger than those currently supplied to Tesla, meaning the U.S. electric vehicle (EV) maker will be able to lower production costs.
