▎ 摘  要

NOVELTY - Composite adhesive comprises adhesive component and styrene-butadiene rubber, the mass ratio of the adhesive component to the styrene-butadiene rubber is (5:1)-(1:1). USE - The composite adhesive is useful for lithium-sulfur battery anode. ADVANTAGE - The composite adhesive: has good flexibility, strong adhesion, high elongation and high tensile strength. The lithium-sulfur battery anode: has high sulfur loading and high areal density; and is simple to prepare which is easy to implement and can realizes large-scale production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Lithium-sulfur battery anode comprising the composite adhesive; and (2) Preparing the lithium-sulfur battery anode comprising (1) mixing the anode active material and conductive agent, and first stirring to obtain the first material; (2) adding the adhesive component to the first material, second stirring to obtain the second material; (3) adding solvent to the second material, and third stirring to obtain the third material; (4) adding styrene-butadiene rubber to the third material, and fourth stirring to obtain anode slurry; and (5) coating the anode slurry on both sides of the anode current collector to obtain a coating layer, drying, rolling it to obtain a lithium-sulfur battery anode.
