摘要： In the nonaqueous electrolyte secondary battery, the positive electrode active material is composed of a mixture of a lithium-cobalt composite oxide containing at least both zirconium and magnesium, and a lithium-manganese-nickel composite oxide containing at least both manganese and nickel. The nonaqueous electrolyte includes fluoroethylene carbonate and dimethyl carbonate as a nonaqueous solvent and further includes an additive expressed by General Formula (1), which having a capability to form an SEI surface film, and a higher oxidation resistance than that of VC. Thus, the negative electrode active material is unlikely to react with the organic solvent. Therefore, decomposition of the organic solvent is suppressed. Thus the battery having a long cycling life even when it is charged at a positive electrode charging potential of 4.4 to 4.6 V based on lithium and having a high residual capacity after storage at high temperature in a charged state is provided.
