Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lithium secondary battery which has a high energy density and a high output. SOLUTION: A manufacturing method of the nonaqueous lithium secondary battery provided with a cathode, anode and a nonaqueous electrolyte includes a cathode molding process (1) in which a cathode material, which is composed of a mixture between a porous carbon material of a specific surface area of 500 m2/g or more in a BET method or the porous carbon material of a specific surface area of 500 m2/g or more in a BET method and a material which can absorb and discharge lithium, is molded into an electrode, an anode forming process (2) in which an anode material of a specific surface are of 20-1,000 m2/g in a BET method, on the active carbon surface of which the carbon material is coated, is molded into an electrode, and a process (3) in which lithium is doped in the anode obtained in the process (2) to obtain a lithium doped anode.
