Panasonic Holdings Corp, which makes batteries for Tesla, said on Wednesday it had shipped samples of its more powerful 4680 format electric car battery to the U.S
Panasonic said mass production of the new battery is set to begin in its new fiscal year starting March next year at its plant in Wakayama in Japan, before production is moved to North America. His remarks at the presentation were the clearest indication Panasonic has given yet that it will build a new plant in the United States to feed Tesla's EV expansion plans.
