Questions tagged [battery]

A battery is a portable electrical power source which is often used in mobile devices.

An electric battery is a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy.

Each cell contains a positive terminal, or cathode, and a negative terminal, or anode. Electrolytes allow ions to move between the electrodes and terminals, which allows current to flow out of the battery to perform work.
