    it is the chemical energy, since each battery is a chemical source of electric energy

    substantially a chemical cell, is a reactor which contains a solution of some acid, and two electrodes. Those electrodes are separated, inside the reactor, by a porous septum, which permits to the ion inside the cell to go from one electrode to another one. Externally, to the reactor there is a wire, and into that wire a current of electrons flow from one electrode to the other one, like this: |dw:1433101872932:dw|
