PURPOSE:To provide a secondary battery having high output and energy density, and a long cycle life, while ensuring freedom from a drop in charge and discharge capacity and efficiency, and battery voltage due to the repetition of charge and discharge cycles. CONSTITUTION:In a nonaqueous electrolytic liquid secondary battery using an inorganic compound as a positive electrode active material, a compound containing titanium added to a lithium cobalt compound oxide in solid solution state is used as the positive electrode active material. |
