Electric battery - Wikipedia
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [ 1 ] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [ 2 ] The terminal marked negative is the source of electrons.
