Zusammenfassung:PROBLEM TO BE SOLVED: To provide a means for compensating irreversible capacity with rise of internal resistance of a battery restrained, through prevention of excessive exothermic reaction between lithium and an anode active material and ensuing softening of a binder. SOLUTION: An anode for a lithium-ion secondary battery includes a collector, an anode active material layer containing an anode active material and a binder with a melting point of 190°C or more formed on the surface of the collector, and a layer containing metal lithium arranged on the surface of the anode active material layer.
