The Chemistry Behind Your Phone's Battery

Your phone is powered by a tiny chemical battle between metals. It's all about electrochemistry. You have "base"

metals like zinc that are super generous and just want to give away their electrons.

Then you have "noble" metals like copper or silver that are eager to take them. In a battery,

we separate these metals, each in its own salt solution, and connect them

with a wire. The electrons then flow from the giving metal to the taking metal through that

wire. That flow of electrons is electricity! It's a controlled chemical reaction

that powers your world until one of the metals is used up.
