Explore the science of why single-use and rechargeable batteries die, and find out why recycling batteries can be challenging.

--

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.

Lesson by George Zaidan, directed by Luisa Holanda.
