    摘要: 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

    摘要: Disclosed is a non-aqueous electrolyte secondary battery having an electrode group in which a positive electrode and a negative electrode are spirally wound with a separator interposed therebetween. The positive electrode contains a positive electrode active material and a binder. The positive electrode active material contains a mixture of two different particulate substances having different average particle sizes. The two different particulate substances are lithium composite metal oxides containing nickel as an essential element. The binder includes fluorocarbon resin and rubber particles. The fluorocarbon resin contains at least a vinylidene fluoride unit. The amount of the rubber particles per 100 parts by weight of the fluorocarbon resin is 1 to 25 parts by weight.
