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.
