LG Energy Solution, a key battery supplier for GM, has reportedly signed a $4.3 billion battery deal to supply lithium iron phosphate batteries to Tesla.

South Korea's LG Energy Solution has signed a $4.3 billion deal to supply Tesla with energy storage system batteries, said a person familiar with the matter, as the U.S. company looks to reduce reliance on Chinese imports due to tariffs.
