Technically, batteries are always being used for energy storage. However, in this industry, saying they will be used for “energy storage” means for stationary energy storage systems rather than in electric vehicles.

Anyway, the largest battery maker in the world, China’s CATL, has said that it expects energy storage will come to account for 50% of its battery sales by 2030, up from 25% today.

If that seems like a crazy increase, note that approximately 2% of CATL’s battery sales were for energy storage five years ago. Also note that CATL is only 15 years old, founded in 2011 just as the EV revolution was getting going.
