PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery having high capacity and high safety. SOLUTION: This secondary battery having a positive electrode active material of a lithium-containing complex oxide, a negative electrode active material for storing and releasing lithium ions, and a nonaqueous electrolyte is used at not more than a prescribed voltage that is less than a nominal voltage. A lithium amount corresponding to a charge capacity D of an expression A- B<=D<=C-A is precharged in the negative electrode active material, wherein A denotes a discharge capacity of the battery when the battery is charged to the nominal voltage, B denotes a discharge capacity of the battery when the battery is charged to the prescribed voltage less than the nominal voltage, and C denotes a maximum reversible discharge amount of the negative electrode active material. |
