Contemporary Amperex Technology Company Limited (CATL) is the current world leader in manufacturing batteries for electric vehicles, owning 37% of the entire market share. Nearly every major car manufacturer, from Ford to Tesla, is using CATL batteries.

In April of 2023, CATL announced its "condensed battery" packing over twice the energy density of nearly anything else on the market at an incredible 500 Wh/kg. For reference, a typical lead acid car battery can have upwards of 50 Wh/kg, while lithium-ion EV batteries like those in the Tesla Model 3 can pack up to around 265 Wh/kg.
