SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a secondary battery capable of obtaining a desired battery capacity by improving charge/discharge efficiency, and a method of manufacturing the same.SOLUTION: An active material base 2 mainly composed of a multi-electron organic compound (a dithione compound, a dione compound, a diamine compound, or the like) is formed on a surface of a positive electrode collector 1 formed of an aluminum foil or the like, and a surface of the active material base 2 is coated with an inorganic active material layer 3 of LiNiMnCoOor the like. The active material base 2 and the inorganic active material layer 3 form a positive electrode active material 4, and the positive electrode active material 4 and the positive electrode collector 1 constitute a positive electrode 5. Active material particles 11 may be coated with an inorganic active material film instead of the inorganic active material layer 3.
