▎ 摘　　要

NOVELTY - Graphene passivation solution comprises 1 -20 wt.% multilayer graphene, 2.5-20 wt.% water-based acrylate, 0.1-10 wt.% silane oligomer, 0.1- 1 wt.% glacial acetic acid, 2-5 wt.% alcohol additives, 0.1-5 wt.% water-soluble dispersant and water (remaining amount), where the water-soluble dispersant includes anionic dispersant and nonionic dispersant and graphene passivation solution does not contain chromium. USE - The passivation solution is useful for soft aluminum-plastic film of lithium battery (all claimed). ADVANTAGE - The graphene passivation solution imparts high adhesive force to the surface of the aluminum foil, and can obtain the ideal composite strength when compounding the film materials e.g. nylon and polypropylene film in the later period. The graphene main body is a material taking carbon element as substrate, the performance is stable, no matter the process of using process or later lithium the incineration process of the battery soft aluminum-plastic film waste, will not generate the harmful substance to the environment and human body. The anion and non-ionic dispersant are combined as the water-soluble dispersant of the passivation system, generating ionization rejection and steric hindrance effect and achievs more excellent stable dispersion. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing graphene passivation solution comprising (i) mixing and stirring silane oligomer and water; (ii) mixing gained material with glacial acetic acid and carrying out hydrolysis reaction, insulated and stirring; (iii) completing hydrolysis and mixing material with the alcohol auxiliary agent; (iv)mixing and stirring the material with water-based acrylate; (v) mixing and stirring the material with an aqueous dispersant to obtain a mother liquor; and (vi) gaining mother liquor is mixed and stirred with multi-layer graphene; lithium battery soft-packed aluminum-plastic film comprising aluminum foil in the lithium battery soft-packed aluminum-plastic film treated with the graphene passivation solution; and lithium battery, comprising the lithium battery soft-wrapped aluminum-plastic film. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of soft aluminum-plastic film inner layer. 1Polypropylene film layer 2Passivation layer 3Aluminum substrate layer
