Anode for lithium secondary battery, fabricating method thereof and lithium air battery having the same

摘要

Provided is an anode for a lithium secondary battery capable of improving the performance and the life of a lithium air battery by forming the anode so that lithium metal is sealed, but migration of lithium ions is possible, and thus, preventing corrosion of a lithium metal and the generation of hydrogen gas caused by permeation of moisture and oxygen gas into the anode, a manufacturing method thereof, and a lithium air battery containing the same.

主权项

1. A manufacturing method of an anode for a lithium secondary battery comprising:
preparing a current collector; laminating a lithium metal on the current collector; laminating a separator on the lithium metal, the separator containing an electrolyte; laminating a solid electrolyte on the separator to form a laminate formed of the current collector, the lithium metal, the separator and the solid electrolyte, wherein the current collector, the lithium metal, the separator and the solid electrolyte have a same circumferential contour shape forming a lateral side surface of the laminate; pressing the laminate in the laminating direction; in the pressed state, applying or coating the lateral side surface of the laminate with any one selected from an adhesive, sealant (water-repellent) and rubber to form a sealing part on the lateral side surface of the laminate; curing the sealing part in the pressed state; and releasing the pressed state after the sealing part is cured to form a cured sealing part.
