PROBLEM TO BE SOLVED: To solve such a problem that conventional positive electrode active material-conductive carbon composite particles have low ion conductivity in a conductive carbon material, so that favorable battery performance cannot be obtained.SOLUTION: Positive electrode active material-conductive carbon composite particles in the present invention have voids moderately, thereby imparting high electronic conductivity and high ion conductivity to a positive electrode active material for a lithium battery. By using the positive electrode active material-conductive carbon composite particles of the present invention, a lithium ion secondary battery having high capacity and high output can be obtained. |
