(57) Abstract: A positive electrode active material capable of suppressing Mn elution from a manganate-based positive electrode active material and achieving excellent battery characteristics, a positive electrode paste using the same, a positive electrode prepared from the paste, And a non-aqueous electrolyte secondary battery using the positive electrode. A method for producing a positive electrode active material containing a conductive polymer having a π-electron conjugated structure and a manganese oxide includes: A positive electrode active material, wherein the manganese oxide is a composite oxide mainly composed of lithium, manganese and oxygen, and the surface of the composite oxide is coated with a conductive polymer by chemically oxidizing and polymerizing a polymerizable compound; The problem is solved by the manufacturing method described above. |
