Tesla Inc. has signed a three-year deal with Japan’s Panasonic Corp. relating to the manufacture and supply of lithium ion battery cells at the Gigafactory in Nevada, the electric carmaker disclosed in a filing Tuesday.
Tesla and Panasonic have been reported to be in talks to expand the battery joint venture’s capacity.
Panasonic hinted in May that it was working to develop new batteries with Tesla, possibly with higher capacity.
