The world's largest manufacturer of EV batteries has just been blacklisted in the US. What do tariffs and blacklists mean for the auto industry - and the U.S. consumer?

Other battery suppliers do exist, but CATL still holds the largest market share. Directly behind CATL is another Chinese supplier, BYD/FinDreams, which also doubles as an EV manufacturer. Korea-based LG Energy Solution sits as the third-largest supplier, while Panasonic, a Japanese-based electronics company, is the fourth-largest.

The automaker has long faced pushback over its plan to license Chinese battery technology at its multibillion plant in Michigan.
