▎ 摘　　要

NOVELTY - The electrode has an electrode film modified by a first thin layer and a second thin layer. The electrode film comprises a first and a second surface, where the first surface is being optionally pretreated. The first thin layer comprises an inorganic compound in a solvating polymer and optionally an ionic salt and/or a plasticizer. The first thin layer is arranged on the first surface of the electrode film and has an average thickness of approximately 15 m or least. The mass ratio of inorganic compound in a solvating polymer in the first thin layer is in the range of about 1:20 to about 20:1. The second thin layer comprises a solvating polymer, an ionic salt and optionally a plasticizer. The second thin layer is placed on the first thin layer and has an average thickness of approximately 15 m or less. The solvating polymer of the first layer is the same as or different from the solvating polymer of the second layer. USE - Electrode for electrochemical battery such as lithium-ion batteries comprising electrochemical cell used in mobile device or portable device e.g cell phones, cameras, tablets and laptops, electric or hybrid vehicle, or in storage of renewable energy (all claimed). ADVANTAGE - The lithiums are used to help stabilize cycling. The improvement of the interface between the self-supporting polymer electrolyte and the anode is clearly visible since an initial discharge capacity is obtained. The overall resistance of the batteries is reduced. The reproducibility is very good using polymer layers on lithium and on cathode. The coulombic efficiencies are also better for cells with modified cathodes and anodes. Two cells with the modified lithium have better reproducibility and do not show a progressive gain in capacity over the first two cycles. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: an electrochemical cell; and an electrochemical battery comprising electrochemical cell. DESCRIPTION OF DRAWING(S) - The drawings show the schematic illustrations of different cell configurations comprising a polymer and inorganic compound layer on the anode including a polymer electrolyte, a polymer layer on the cathode and a polymer electrolyte, a second layer without inorganic compound on the sum of polymer and inorganic compound layer and a polymer electrolyte, a second layer without inorganic compound on sum of the polymer and inorganic compound layer, a polymer layer on the cathode, and a second layer without inorganic compound on the sum of polymer layer and inorganic compound.
