摘要： An object is to improve the cycle performance by improving the reactivity between lithium and a negative electrode active material in the case where an alloy-based material such as silicon is used as the negative electrode active material. A method of manufacturing a lithium secondary battery including a positive electrode including a positive electrode active material into/from which lithium can be inserted/extracted, a negative electrode including a negative electrode active material into/from which lithium can be inserted/extracted, and an electrolyte solution is provided. The method includes the steps of electrochemically inserting lithium into the negative electrode with use of a counter electrode before the lithium secondary battery is assembled, electrochemically extracting part of the lithium inserted into the negative electrode after the insertion, and assembling the lithium secondary after the extraction.
