Abstract

A method for manufacturing a negative electrode for a lithium secondary battery. A negative electrode for a lithium secondary battery is manufactured while forming a composite of lithium metal and a negative electrode active material through a rolling process In the case of the lithium secondary battery to which the negative electrode containing such a composite is applied, when the battery starts to operate, the negative electrode active material is pre-lithiated, and thus charging/discharging process proceeds in the state where the lithium alloy is already formed on the negative electrode, thereby showing an effect of reducing initial irreversible phases.
