NOVELTY - Preparing lithium-ion battery cathode comprises (i) preparing raw material, primarily mixing binder, dispersant, conductive agent and water, and adding into a tank body; (ii) preparing graphene, lithium titanate and titanium niobate, adding to a grinding cylinder for grinding treatment to obtain mixed material; (iii) adding the mixed material into a discharge mixing cylinder after scattering; (iv) making the mixed material enter into the tank body through a circulating hole at the side part of the discharging mixing cylinder; and (v) adding the processed material into a ball mill for ball milling, drying, calcining, cooling, crushing, and sieving. USE - Method for preparing lithium-ion battery cathode. ADVANTAGE - The composition: limits the flow rate of graphene and other powdered materials; and reduces the influence of the binder on graphene and other powdered materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for lithium-ion battery cathode, comprising 30-45 pts. wt. graphene, 20-30 pts. wt. lithium titanate, 10-15 pts. wt. titanium niobate, 0.1-0.3 pts. wt. sodium dodecyl sulfate, 0.1-0.3 pts. wt. poly(vinylidene fluoride) binder, 0.1-0.3 pts. wt. acetylene black, and 100-150 pts. wt. water. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the tank body and grinding cylinder. 1Tank body 2Cover 41Grinding cylinder 42Discharging mixing cylinder
