Abstract: The present invention relates to the technical field of battery binders, and to a water-based positive electrode edge coating adhesive and a use thereof, and a positive electrode sheet edge coating slurry. The technical problem solved by the present invention is to provide a water-based positive electrode edge coating adhesive. The water-based positive electrode edge coating adhesive comprises a graft polymer. The graft polymer has an acrylic polymer as a backbone and is grafted with polymer latex particles, and the weight percentage of the polymer latex particles in the graft polymer is 20-80%. Polymerization monomers for the acrylic polymer include an acrylic monomer, an acrylamide monomer, and a hydroxyalkyl acrylate monomer; and polymerization monomers for the polymer latex particles include a crosslinking monomer and a double-bond monomer. The water-based positive electrode edge coating adhesive of the present invention can be used as a positive electrode sheet edge coating adhesive, has good adhesion with an aluminum foil, and shows that an electrode sheet does not fall off when being pulled by means of an adhesive tape. In addition, the water-based positive electrode edge coating adhesive has certain toughness, shows no foil exposure when being folded by 180ยบ, and does not easily fall off after being soaked in an electrolyte solution and then being wiped.
