摘要：

PURPOSE:To enhance performance of a nonaqueous electrolyte secondary battery. CONSTITUTION:In a nonaqueous secondary battery using a carbon material such as coke and graphite as a negative active material, a positive electrode 2 is prepared by using a mixture of a lithium containing composite oxide (for example, LiMn2O4 or LiCoO2) and a lithium-titanium composite oxide represented by a general formula, Li1+x Ti2-xO4 (0<=x<=0.17) as an active material. Elution of a negative current collector 1 in overdischarge is prevented, and the battery free from remarkable deterioration in performance is provided.
