<P>PROBLEM TO BE SOLVED: To provide the manufacturing method of a positive plate for a nonaqueous system secondary battery capable of uniformly dispersing mix coating material even when mixing amount of materials other than active material contributing to battery capacity is decreased and decreasing the scattering of the coated mass; and to provide the nonaqueous system secondary battery using a positive plate by this manufacturing method and having excellent charge discharge cycle characteristics. <P>SOLUTION: An active material A, a hydrophilic treated conductive material B, a thickening agent D, and a water system dispersing agent which is a divided dispersing agent E are wetted and primarily kneaded, and then a binder C and the divide remaining dispersing agent E are added and kneaded to prepare the mix coating material, and the mix coating material is applied to a current collector and dried. <P>COPYRIGHT: (C)2008,JPO&INPIT |
