Title:
METHOD FOR MANUFACTURING LITHIUM SECONDARY BATTERY AND METHOD FOR CHARGING LITHIUM SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2021/206121
Kind Code:
A1
Abstract:
This method is for manufacturing a lithium secondary battery comprising an aluminum negative electrode which can occlude and discharge lithium ions, a positive electrode which can occlude and discharge lithium ions, and an electrolyte. The aluminum negative electrode comprises an aluminum-containing metal. The method has: a step for assembling the lithium secondary battery; a step for charging the assembled lithium secondary battery; a step for storing the charged lithium secondary battery for at least four hours; and a step for inspecting the capacity of the lithium secondary battery after the storing step.
