Electric Battery

electricity · chemistry · power

Electrons on the move. A battery's negative side pushes out electrons, which travel through your device and return to the positive side, making electricity flow like water through a pipe.

Chemical reaction inside. Inside a battery, chemicals react together and release energy, converting high-energy materials into lower-energy ones while sending that leftover energy to power your phone or toy.

Two ends, two jobs. The positive terminal (cathode) attracts electrons, while the negative terminal (anode) sends them out, like a seesaw where one side pushes and the other side pulls.

One cell or many. A single battery cell works alone, but people used to call it a "battery" only when multiple cells were stacked together, now we use the word for both!

Redox reaction power. The chemical reaction in a battery is called a redox reaction, where electrons move between materials and release energy that gets converted into electrical power.
