Almost all batteries, even single-use batteries, are theoretically rechargeable. That's because the metals and other chemicals are still there in the battery. So chemically speaking, a dead battery is actually not that different from a fresh one. Then why do batteries die in the first place? And what should you do with them once they're spent? George Zaidan digs into the science of batteries. [Directed by Luisa Holanda, narrated by George Zaidan, music by Gabriel Maia]. After the talk, Sherrell reflects on the future of recycling batteries and the important role it plays is supporting sustainable energy.
