摘要:
Provided is a method for manufacturing a lithium secondary battery which is capable of preventing a local deposition of a metallic foreign substance at a negative electrode regardless of the type of a positive electrode and in which a short-circuit is less likely to occur. The present manufacturing method comprises: a step of assembling a cell that includes a positive electrode, a negative electrode, and a nonaqueous electrolyte; a micro charging step of performing a micro charge on the assembled cell before performing an initial conditioning charge until a positive electrode potential with respect to a metal lithium (Li) reference electrode exceeds an Me dissolution potential set in advance at which a mixing-anticipated metal species (Me) starts to dissolve; and an Me dissolution potential holding step of holding the positive electrode potential of the cell at or above the Me dissolution potential for a prescribed period of time after the micro charge.
