PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery, having improved input/ output characteristics at a low-temperature and improved battery performance stability during overcharging. SOLUTION: The nonaqueous secondary battery uses an active material containing, predominantly lithium manganate for a positive electrode, a carbon material having a lithium insertion coefficient K of 0.70<=K for a negative electrode and a nonaqueous electrolyte as an electrolyte. |
