ABSTRACT:
An electrode for a rechargeable electrochemical cell including an electrically conductive substrate, a layer of an electrochemically active material attached to the substrate, the active material comprising a reducible species of a metal, at least one conductive contact area formed of a metallic form of said metal attached to said substrate, said metallic contact area comprising said reducible species in a converted form. A positive electrode is further provided wherein said active material is nickel hydroxide and said metallic form of said metal is nickel metal. The invention further comprises the method for manufacturing electrodes as described above, featuring use of reducing gas to effect conversion.
