SECONDARY BATTERY AND METHOD FOR PRODUCING SECONDARY BATTERY

摘要

An active material substrate (2) having a many-electron organic compound (dithione compound, dione compound, diamine compound, or the like) as the main body thereof is formed at the surface of a cathode collector (1) formed from aluminum foil or the like, and furthermore, the surface of the active material substrate (2) is covered by an inorganic active material layer (3) such as LiNiMnCoO2. A cathode active material (4) is formed by the active material substrate (2) and the inorganic active material layer (3), and a cathode (4) is configured from the cathode active material (4) and the cathode collector (1). In place of the inorganic active material layer (3), active material particles (11) may be covered by an inorganic active material film. As a result, a secondary battery able to obtain a desired battery capacity and having increased charging/discharging efficiency and a method for producing the secondary battery are achieved.
