Abstract: A method for charging a non-aqueous electrolyte secondary battery, the battery comprising a positive electrode that comprises a lithium-containing composite oxide, a negative electrode, and a non-aqueous electrolyte. The method comprises the step of detecting an open-circuit-voltage of the battery to determine which of voltage regions A, B and C the detected value is included in. The region A is not smaller than a prescribed value X. The region B is smaller than the prescribed value X and larger than a prescribed value Y (Y

Abstract: The non-aqueous electrolyte-containing secondary battery of the present invention uses a non-aqueous electrolyte including at least one phosphoric ester derivative expressed by Formula (1): (R1aO)(R2aO)P(O)X and by Formula (2): R(1bO)P(O)X2, wherein R1a, R2a, and R1b independently denote aliphatic hydrocarbon groups having 1 to 12 carbon atoms and X denotes a halogen atom. This arrangement improves the high-temperature storage characteristics after charging and the charge-discharge cycle characteristics of the secondary battery.
