EV battery recycling and reuse is an active and growing industry. Retired EV batteries that no longer meet the range needs of a vehicle still often retain 70–80% of their original capacity, making them suitable for stationary energy storage — such as storing solar power at homes or grid-level storage.
When batteries reach end-of-life for any use, they can be recycled to recover lithium, cobalt, nickel, and manganese for use in new batteries. Companies like Redwood Materials and battery manufacturers are investing heavily in closed-loop recycling. Most major automakers have battery take-back and recycling programs.
