How It’s Made Lithium Ion Batteries

Watch Lithium Ingot Turn Into Car Batteries

Lithium is the lightest of all metals (the third element in the periodic table), has the greatest electrochemical potential, and provides the highest energy density. This video from How it’s Made shows how an 11-pound lithium ingot is extruded and rolled to a thickness of 0.01 in. and length of 1.25 miles, enough to make 210 battery units.
