1. A method for cathodically protecting and/or passivating a metal section in an ionically conductive material, comprising:

  • providing a storage component of electrical energy with two poles;

    providing an anode for communication of an electrical current to the metal section in the ionically conductive material where the anode is of a material which is not sacrificial to the metal section;

    electrically connecting one pole to the metal section, electrically connecting the other pole to the anode and placing the anode in ionic contact with the ionically conductive material such that the electrical current can flow from the storage component through the electrical connection to the metal section;

    wherein the anode comprises at least part of an outer surface of an outer case of the storage component.
