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.

The deal also reduces Tesla’s reliance on Chinese suppliers. LGES will produce the LFP cells at its factory in Michigan, says Reuters, and so they will not be subject to the Trump trade war tariffs, unlike Chinese-made cells from CATL.
