Why your phone battery gets worse over time - George Zaidan

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.
