PURPOSE:To provide high workability and further to provide high performance and high energy density while reducing internal resistance and improving long period reliability and safety by forming a layer, having electronic conductivity, of an ion conductive high molecular compound. CONSTITUTION:Between at least one of positive/negative electrode collectors and a compound positive/negative electrode or an negative electrode mainly composed of alkali metal, a layer, having electronic conductivity, is provided. By forming this layer of a binding agent which is a polymer having acid amide connection and imide group in a principal chain with an electronic conductive grain, adhesion can be improved between the compound positive/negative electrode or the negative electrode mainly composed of alkali metal and the positive/negative electrode collector. By using an ion conductive high molecular compound also by providing the layer having electronic conductivity, even after high temperature long period storage, and even after repeatedly bending a battery, separating an active material layer from the collector is prevented from being generated, and since increasing internal resistance of the battery is suppressed, a battery characteristic can be prevented from decreasing. |
