What if millions of used electric vehicle (EV)  batteries weren’t waste, but instead a valuable resource? 

Drawing on insights from the International Energy Agency and EPO patent data, this episode explores how battery circularity can extend the life of EV batteries, reduce uncertainty around obtaining critical materials like lithium and cobalt, and support a more sustainable energy future. From second-life applications and advanced recycling technologies to policy developments like digital battery passports, discover how innovation is reshaping the lifecycle of batteries.
