Abstract: A unitized electrode-intercell connector module is prepared for use in a bipolar electrode, especially for use in such electrode of the M-alkaline electrolyte-AgO types. In such special electrode, an imperforate foil, contacted with a conductive foam, is plated to a unitized, electrobonded assembly. Pyrolysis can lighten the assembly and may further provide for subsequent resistance to attack in an electrode environment. For the special electrode the reticulate portion of the assembly can be filled to provide an AgO electrode and the bipolar electrode completed by using a suitable electronegative metal on the foil side opposite from the AgO electrode.

Abstract: A reticulate primary electrode, usually cathode, and method for making for use in an electrochemical cell. The cathode is openly porous, in substantial physical contact with a separator used in the cell for separating anode and cathode compartment within the cell, and intermetallically bound to a cathodic current collector used within the cell.
