摘要： A method of manufacturing a secondary battery using lithium metal as a negative electrode, and more particularly, a method of manufacturing a secondary battery capable of removing an oxide film formed on a lithium metal by performing some initial discharges during the initial period of the activation process to thereby improve the cycling performance of the battery by allowing lithium to be uniformly precipitated. The result minimizes the reduction of ion conductivity by removing the oxide film formed on the surface of the lithium metal through the initial partial discharge and improves the battery cycle performance since the precipitation reaction of lithium becomes uniform.
