PROBLEM TO BE SOLVED: To obtain a high-power lithium secondary battery Li1+XMn2-xO4LiMn2 O4 system positive suitable especially for an electric vehicle, especially a hybrid electric vehicle requiring high output. SOLUTION: A high-power lithium secondary battery for a hybrid electric vehicle is obtained, which amorphous carbon and/or black lead is used in its negative electrode, Li1+XMn2-xO4 is used in its positive electrode, and Li1+XMn2- xO4 of both sides of a current collecting body per unit area in the positive electrode is set at 6 to 36 mg/cm2. |
