Retired EV batteries are being repurposed for solar storage, but recycling remains challenging, especially for cobalt-free LFP types, prompting new regulations in China and the EU.
As electric vehicles grow, repurposing retired EV batteries is gaining traction, with a pilot project in Mae Hong Son, Thailand, using old batteries to store solar energy.
Globally, recycling is becoming critical due to the high recoverable lithium and cobalt in used batteries, though transport risks and collection challenges persist, especially in developing regions.
Battery swapping networks in China and Vietnam offer alternatives, but Thailand’s PTT shut down its program in 2026 due to market issues.
A major hurdle is recycling lithium iron phosphate (LFP) batteries, which lack cobalt and nickel, making them less profitable.
China has responded with strict regulations, including a national tracking system and approved recyclers, while the EU will require digital Battery Passports by 2027 to track origin and environmental impact.
Las baterías retiradas de vehículos eléctricos se están reutilizando para el almacenamiento solar, pero el reciclaje sigue siendo un desafío, especialmente para los tipos de LFP sin cobalto, lo que provocó nuevas regulaciones en China y la UE.
