Title:
METHOD FOR PREPARING ANODE MATERIAL FOR LITHIUM METAL BATTERY BY USING GRAPHENE-PRETREATED SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2024/085296
Kind Code:
A1
Abstract:
A method for preparing an anode material for a lithium metal battery according to the present invention comprises the steps of: preparing a current collector substrate foil; pretreating a first surface of the current collector substrate foil by wet or dry coating of graphene; pretreating a second surface, as the counter surface, of the current collector substrate foil by wet or dry coating of graphene; laminating lithium metal foil to both the graphene-pretreated substrate surfaces by a press roll to form an anode material; and winding the laminated anode material.
