<P>PROBLEM TO BE SOLVED: To provide a positive electrode for a lithium battery that allows the prevention of the increase of the internal resistance of the lithium battery, after a long-term storage, without performing a thermal treatment precess at a high temperature after adding an additive to manganese dioxide, and that also allows a long-term good maintenance of the properties that the lithium battery has when a large current is drawn therefrom. <P>SOLUTION: Boron oxide is dissolved in water, and an aqueous solution of boron oxide is prepared (S1). The boron oxide aqueous solution is mixed with manganese dioxide, to be fully impregnated (S2). After the mixing, drying is performed to prepare manganese dioxide containing boron is prepared (S3). The manganese dioxide containing boron, carbon powder as a conductive agent, tetrafluoroethylene and water are mixed together to be kneaded (S4). The thus prepared kneaded mixture is formed into a sheet (S5), and adhered to a lath core with pressure, which is then dried and extended by applying pressure to form a positive electrode plate (S6). <P>COPYRIGHT: (C)2010,JPO&INPIT |
