This lithium secondary battery contains: a positive electrode having a positive electrode active material capable of occluding and discharging lithium ions; a negative electrode having a negative electrode active material capable of occluding and discharging lithium ions; a separator positioned between the positive electrode and the negative electrode; and an electrolyte having lithium ion conductivity. Therein, the positive electrode active material contains a lithium nickel complex oxide having a substantially irreversible capacity, lithium is occluded in the negative electrode active material in advance, and when the lithium secondary battery is in a state of complete discharge and the ambient temperature is 25°C, the amount of lithium in the negative electrode capable of being discharged is greater than the irreversible capacity of the lithium secondary battery. |
