Abstract
A long-life battery whose properties do not deteriorate after charge-discharges cycles is provided. A non-aqueous electrolyte secondary battery includes a cathode, an anode, and a non-aqueous electrolytic solution containing an electrolyte. At least one of the cathode and the anode includes a binder. The binder includes a layer having electron conductivity on a surface thereof. The binder improves the contact property between particles of the active materials of the battery and the conductivity in the electrode without impairing the binding property of the binder. Preferably, the binder includes a metal on the surface thereof and the metal does not form an alloy with lithium to further improve the lifetime of the battery.
