The present invention is related to a lithium secondary battery provided with a cathode, an anode, and a nonaqueous electrolyte with lithium ion conduction set between the cathode and the anode, wherein the cathode has a cathode active material including at least one chemical element selected from a group of silicon and tin. In a completely charged state of the lithium secondary battery charged bya predetermined charging method, the cathode active material and the anode active material respectively are in a first partially charged state, and in a completely discharged state of the lithium secondary battery discharged by a predetermined discharging method, the cathode active material and the anode active material respectively are in a second partially charged state. The battery design in combination of the charged state of the cathode active material and the anode active material can provide a lithium secondary battery with an excellent charge-discharge cycle characteristic.
