Method for producing a negative electrode for a method and a lithium secondary battery of doping and dedoping lithium anode

The purpose of this embodiment is to provide a negative electrode having excellent cycle characteristics. This embodiment is a method of first doping and dedoping lithium from being produced in the negative electrode for a lithium secondary battery containing silicon oxide as the active material, in the following current value range (A), and the following the doped amount range (B), doped lithium, characterized and de-doping method to dope the lithium; current value range (a); and the voltage V to lithium reference electrode of the negative electrode, the change of the voltage V and dQ / dV with respect to the amount dV is the ratio of the change amount dQ of the negative electrode lithium dedoping amount Q, on V-dQ / dV curve representing the relationship, the doping amount is maximum appearing peak below 1V is only one the range of the current value at which, the doping amount range (B); in the V-dQ / dV on the curve, range peak below 1V is only appears doping amount one.
