PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery which can deliver a desired battery performance with stability.SOLUTION: A nonaqueous electrolyte secondary battery 100 proposed here is manufactured by performing an initial charge/discharge process on an assembly arranged by enclosing an electrode body 40 and a nonaqueous electrolyte in a battery case 80. The nonaqueous electrolyte includes a compound expressed by the general formula: A[PX(CO)]. In the nonaqueous electrolyte, the content of the compound is 1.1-1.2 mass% to a total of 100 mass% of the nonaqueous electrolyte.SELECTED DRAWING: Figure 1 |
