Abstract: An apparatus for supplying power to a motor vehicle, in particular a passenger vehicle or motorcycle, has a plurality of electrochemical storage cells. At least one of the electrodes respectively situated in the storage cells is made of metal or is provided with a metal layer essentially over its entire surface.
