<P>PROBLEM TO BE SOLVED: To achieve a positive electrode plate for nonaqueous electrolyte secondary battery which has high capacitance (highly filled) and high electron conductivity, and is strong by solving the problem that high efficient charging/discharging characteristics and cycle characteristics decrease when a conductive agent and a binder are reduced for high capacity of battery, in the case of manufacturing the positive electrode plate by a conventional method. <P>SOLUTION: In the nonaqueous electrolyte secondary battery, particularly in a manufacturing method of the positive plate, when kneading, to uniform the dispersion of the conductive agent and the binder, a positive electrode active material where DBP absorbed amount is below 20 ml/100 g is used. <P>COPYRIGHT: (C)2007,JPO&INPIT |
