▎ 摘　　要

NOVELTY - The protective layer comprises the raw material of the protective layer which is mainly active material 70 to 90 %, conductive agent 5 to 15 % and agglomerant to 15 %. The agglomerant can be polyvinylidene fluoride, sodium carboxymethyl cellulose and polyacrylic acid. The conductive agent can be carbon black, acetylene black, graphite, graphene, oxidized graphene and carbon nano tube. The active material is polyphenylene sulphide-based strong acid ion exchange fibre, polyphenylene sulphide-based strong acid ion exchange. USE - Protective layer of aqueous zinc ion battery metal zinc negative electrode. ADVANTAGE - The layer improves the cycle stability and electrochemical performance of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing aqueous zinc ion battery metal zinc negative electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a protective layer of aqueous zinc ion battery metal zinc negative electrode.
