A method for producing a rechargeable battery in the form of a multi-layer coating in one embodiment includes applying an active cathode material above an electrically conductive and electrochemically compatible substrate to form a cathode; applying a solid-phase ionically-conductive electrolyte material above the cathode as a second coating to form an electrode separation layer; applying an anode material above the electrode separation layer to form an anode; and applying an electrically conductive overcoat material above the anode. A method for producing a multi-layer coated cell in another embodiment includes applying an anode material above a substrate to form an anode; applying a solid-phase electrolyte material above the anode to form an electrode separation layer; applying an active cathode material above the electrode separation layer to form a cathode; and applying an electrically conductive overcoat material above the cathode. Cells are also disclosed.
