<P>PROBLEM TO BE SOLVED: To provide a positive plate capable of increasing capacity by reducing binding material and thickening agent, expanding life by reducing irregularity of coating weight and improving high temperature keeping properties by reducing conductive material by using an even dispersal effect of electrode plate structuring materials by improving the conductive material, the binding material and the thickening agent which are structuring materials other than an active material contributing to battery capacity and a large capacity nonaqueous secondary battery using the positive plate. <P>SOLUTION: In the electrode panel structured by mixing and dispersing the active material A, the conductive material B, the rubber particle binding material C having acrylate units and the thickening agent D of water soluble polymer in water, the active material A and the conductive material B is moistened with water solution of the thickening agent D as a first mixing and then the binding material C and water are added and mixed. In the above procedure, the binding material C is 0.2 to 1.4 pts.wt. of the active material A and viscosity of 1 wt.% water solution of the thickening agent D is 2.5 to 18Pa s. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
