NOVELTY - The method comprises applying (702) an active cathode material above an electrically conductive substrate to form a cathode, applying (704) a solid-phase ionically-conductive electrolyte material above the cathode as a second coating to form an electrode separation layer, applying (706) an anode material above the electrode separation layer to form an anode, and applying (708) an electrically conductive overcoat material above the anode. The active cathode material includes an ion-conductive polymer as part of a binder phase to facilitate ion transport in interstitial spaces of the cathode.    USE - The method is useful for producing rechargeable lithium ion battery in the form of multi-layer coating, where the rechargeable lithium ion battery is useful in nickel metal hydride system and proton exchange membrane fuel cells.    ADVANTAGE - The method is capable of economically, easily and safely producing the rechargeable battery with high reliability and energy storage capability, increased energy density, less number of processing steps and improved performance and without any damage or failure to the battery.    DETAILED DESCRIPTION - The method comprises applying (702) an active cathode material above an electrically conductive substrate to form a cathode, applying (704) a solid-phase ionically-conductive electrolyte material above the cathode as a second coating to form an electrode separation layer, applying (706) an anode material above the electrode separation layer to form an anode, and applying (708) an electrically conductive overcoat material above the anode. The active cathode material includes an ion-conductive polymer as part of a binder phase to facilitate ion transport in interstitial spaces of the cathode. The ion-conductive polymer is provided between particles of the active cathode material. The anode material, cathode material and/or electrolyte material includes particles having a shape consisting of round, oval, cylindrical, prismatic and irregular shape. The ion-conductive polymer in the binder phase comprises a polymer with anionic sulfonate groups substituted onto a carbon-based backbone, is combined with conventional binder materials, and is used in conjunction with polyvinylidene fluoride to form the binder phase. The anode includes an ion-conductive polymer between particles of active anode material to facilitate transport of cations in interstitial spaces of the anode. The electrode separation layer comprises hard particles of inorganic solid-state lithium-ion conductors and inorganic solid-state sodium-ion conductors dispersed in a polymeric binder. The binder is polyvinylidene fluoride, a lithium and sodium ion exchange polymers with high lithium-ion mobility and high sodium-ion mobility, a solid polymer electrolyte, or a polymer-gel electrolyte. The substrate comprises a metal foil. The method further comprises applying an anode material above a substrate to form an anode, applying a solid-phase ionically-conductive 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. An INDEPENDENT CLAIM is included for a lithium ion, other rechargeable, or primary cell formed on a single substrate.
