摘要： In a charge/discharge method for a positive-electrode active material in a lithium secondary battery, the lithium secondary battery includes a positive electrode containing a positive-electrode active material capable of occluding and releasing lithium ions, a negative electrode containing a negative-electrode active material capable of occluding and releasing lithium ions, a separator located between the positive electrode and the negative electrode, and an electrolyte having a lithium ion conductivity; and the positive-electrode active material contains a nickel-type lithium-containing complex oxide. The positive electrode, which has been charged, is discharged until having a first potential VDp1 which is no less than 2.7 V and no more than 3.4 V on a lithium metal basis, and then the discharge is finished. Owing to this, the charge/discharge cycle life can be improved while the capacity of the lithium secondary battery is secured.

摘要： A negative electrode including a negative electrode current collector, first protrusions on a surface of the negative electrode current collector, a separation-stopping area on at least a part of a surface of each first protrusion, and a negative electrode active material layer including a negative electrode active material and formed on at least a top face of the first protrusion. This structure suppresses the separation of the negative electrode active material layer from the negative electrode current collector, the degradation of the current collecting ability, and the deformation of the negative electrode itself. A lithium ion secondary battery including this negative electrode has a high battery capacity, a high energy density, and an excellent charge/discharge cycle characteristic, and is capable of stably maintaining a high power over an extended period of time.
