CONTINUOUS MANUFACTURING METHOD OF LITHIUM RECHARGEABLE BATTERY FORMING PASSIVE FILM ON SURFACE OF LITHIUM METAL ELECTRODE AND LITHIUM RECHARGEABLE BATTERY MANUFACTURED THEREFROM

摘要

The present invention provides a manufacturing method of a lithium rechargeable battery, including (i) preparing a lithium metal electrode in which metal lithium (Li) is formed on one surface or both surfaces of a current collector; (ii) applying an electrolyte solution for coating including one or more lithium salts, one or more non-aqueous organic solvents, and one or more additives on a surface of the metal lithium to form a passive film which is a stable coat; (iii) manufacturing an electrode assembly including the lithium metal electrode as a negative electrode; and (iv) housing the electrode assembly in a rechargeable battery case and injecting an electrolyte solution for injection including one or more lithium salts, one or more non-aqueous organic solvents, and one or more additives to manufacture a rechargeable battery.
