Solid Power (Colorado)
-
Also builds solid-state cells
-
Partners with Ford and BMW
-
Pilot lines under construction
These companies aren’t in mass production yet, but their technology could change the game.
Why This Matters
Batteries are the heart of an EV. The better the battery, the better the car. America wants to lead in this space. That’s why the government is helping companies build more battery plants here.
The main goals are:
-
Bring battery jobs to the U.S.
-
Reduce dependence on China
-
Make EVs cheaper for everyone
Final Thoughts
The U.S. is becoming a global leader in battery production. Companies like SK, LG, and Panasonic already have big operations here. New names like ONE, Freyr, and Redwood are rising fast.
As more people switch to electric cars, these companies will power that change. One battery at a time.
