NOVELTY - A positive electrode (21) consists of positive electrode active material, acrylic resin and carbon-type material. The positive electrode active material is transition-metal complex oxide containing lithium and nickel. A portion of acrylic resin is absorbed by the powder which consists of positive electrode material and carbon-type material. The non-adsorption content of the acrylic resin and total content of positive electrode active material, acrylic resin and carbon-type material, satisfies a preset relation (I).    USE - Positive electrode is used for battery e.g. lithium ion secondary battery used in battery pack, electronic device, electric vehicle, electric storage apparatus, electric power information-control apparatus and electric power system (all claimed) for built-in-camera video tape recorder, mobile telephone and notebook personal computer.    ADVANTAGE - The positive electrode has excellent uniformity of thickness.    DETAILED DESCRIPTION - A positive electrode (21) consists of positive electrode active material, acrylic resin and carbon-type material. The positive electrode active material is transition-metal complex oxide containing lithium and nickel. A portion of acrylic resin is absorbed by the powder which consists of positive electrode material and carbon-type material. The non-adsorption content (B1) of the acrylic resin and total content (A1) of positive electrode active material, acrylic resin and carbon-type material satisfies a relation: (B1/A1)x 100=0.95-1.296 %mass. INDEPENDENT CLAIMS are included for the following:    (1) battery;    (2) manufacture of positive electrode;    (3) electronic device;    (4) electric vehicle;    (5) electric storage apparatus;    (6) electric power information-control apparatus; and    (7) electric power system.
