This week's Cleantech Talk podcast is an "EV battery special." Chris DeMorro and Zachary Shahan talk about new research that highlights the fast-dropping price of electric vehicle batteries, the wide variation in the lifetimes of different lithium-ion battery cells, and Volkswagen's stake in solid-state battery startup QuantumScape. We started off the show chatting about new research highlighting a "hidden benefit" of EVs. Enjoy the show!
