PROBLEM TO BE SOLVED: To provide a non-aqueous secondary battery, which is excellent in reliability over a long period of time, by suppressing capacity degradation by repetition of charges/discharges of electricity in the non-aqueous secondary battery. SOLUTION: An electrode is formed by forming an electrode-applied film which contains a binder and an active material in a surface of a conductive base body. As the binder, a mixture of a polyvinylidene fluoride system polymer and a cellulose-rubber-ester combined system polymer is used. By this, since adhesive property to the conductive base body becomes good comparing with the electrode-applied film of which the binder is constituted from the polyvinylidene fluoride system polymer independent, cell capacity reduction by degrading of the electric junction between the electrode-applied film and the conductive base body, according to the repetitions of a charge/discharge electricity, can inhibited. |
