<P>PROBLEM TO BE SOLVED: To solve a problem in an all-solid polymer battery that, when a porous positive electrode active material with a large pore volume is used, dry polymer electrolyte does not permeate easily in the pores, and contact between the positive electrode active material and the dry polymer electrolyte tends to be insufficient, wherefore, a reaction area of the dry polymer electrolyte and the positive electrode active material gets smaller, and a battery capacity obtained tends to be lower than a theoretical capacity of the positive electrode. <P>SOLUTION: The positive electrode 1 for an all-solid polymer battery contains a positive electrode collector 10 and a positive electrode active material layer 11, which latter 11 contains a porous positive electrode active material, a conductive material and dry polymer electrolyte. The porous positive electrode active material has pores inside it, and, contains high-boiling-point organic matter with a boiling point of 150°C or higher in the pores. Thus, an all-solid polymer battery with a large capacity is obtained, even with the use of the porous positive electrode active material. <P>COPYRIGHT: (C)2010,JPO&INPIT |
