NOVELTY - The battery (101) includes a cathode (107), an anode (108), and a non-aqueous electrolytic solution containing an electrolyte. A binder is provided in the cathode or anode, in which the binder includes a layer having electron conductivity on its surface. The layer with electron conductivity is an electrically conductive layer that includes a metal. The binder includes a metal and carbon on its surface. The metal in the electrically conductive layer and binder may be copper, nickel, iron, titanium, aluminum, or their alloy.    USE - Non-aqueous electrolyte secondary battery e.g. lithium ion battery used in power source and device system. Can be used in electric vehicles, as air secondary battery, and for energy storage.    ADVANTAGE - Provides a long-life battery that includes an electrode having an electronic network in the interior, in which the electronic network is unlikely deteriorating after charge-discharge cycles. Ensures improved contact between particles of the active materials, which allows the battery to have long lifetime. Reduces the amount of binder because the battery active material particles can be electrically bonded efficiently with small amount of the binder added. Ensures that the amounts of the binder and conductive materials are reduced, thus ensuring improved specific energy density of the battery. Ensures that the electron transfer between the battery active material and current collector is not prevented because the binder itself has a conductivity even when the binder covers the surface of the current collector. Ensures that the electronic network inside the electrode is always maintained even when the volume of the battery active material is changed by charge-discharge cycles because the binder is elastic. Extends the lifetime of the battery, which is especially advantageous in cases involving changes in volume of the active material as in charge-discharge cycles.
