▎ 摘  要

NOVELTY - A graphene-lithium battery material comprises 100 pts. wt. lithium titanate, 3-6 pts. wt. graphite, 0.5-2 pts. wt. binder, 0.5-1.5 pts. wt. rare earth compound, 2-5 pts. wt. dispersant, 1-3 pts. wt. defoaming agent and 30-50 pts. wt. organic solvent. USE - Graphene-lithium battery material. ADVANTAGE - The material has large capacity, excellent conductive property and long service life. The method is simple, easy and suitable for industrialization. DETAILED DESCRIPTION - A graphene-lithium battery material comprises 100 pts. wt. lithium titanate, 3-6 pts. wt. graphite, 0.5-2 pts. wt. binder, 0.5-1.5 pts. wt. rare earth compound, 2-5 pts. wt. dispersant, 1-3 pts. wt. defoaming agent and 30-50 pts. wt. organic solvent. The binder is rosin resin, epoxy resin, polyacrylate or ethylene-acrylic acid copolymer. The dispersant is sodium metasilicate pentahydrate, laurinol polyether sodium sulfate, octyl phenol polyoxyethylene ether or sodium alkyl naphthalene sulfonate. The defoaming agent is lauryl ether, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxypropylene ethylene oxide ether or nonyl phenol polyoxyethylene ether. An INDEPENDENT CLAIM is included for preparation of graphene-lithium battery material comprising taking dispersant, antifoaming agent and graphite, adding organic solvent, ultrasonicating for 30-60 minutes, adding binder, stirring for 10-20 minutes, adding remaining raw materials, stirring for 1-2 hours, and drying.
