There was a report that Tesla had signed up Tianjin Lishen as a battery supplier but Elon Musk said this is not true.
Tesla is looking to expand its battery supplier base outside of Panasonic, which has supplied the cells for all of Tesla’s electric vehicles since Tesla started production a decade ago.
In late 2018, Musk said Tesla may source cells from other companies, as long as they meet the exact same specification[s] as the 2170 cells currently used.
