NOVELTY - A lithium ion battery cathode material comprises 10-12 pts. wt. ferric manganese silicate, 5-7 pts. wt. tin chloride, 20-24 pts. wt. red phosphorus, and 20-24 pts. wt. graphene. USE - Lithium ion battery cathode material. ADVANTAGE - The cathode material has good storage performance and high electronic conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of cathode material comprising dissolving ferric manganese silicate in mixed solvent of octanol and polyvinyl alcohol, dissolving tin chloride in 60% ethanol solution, and mixing processed raw materials at ratio of 1:1, and adding graphene, purging nitrogen gas, reacting at 170-240 degrees C, stir-reacting for 0.5-1.5 hours, cooling to 80-95 degrees C, adding red phosphorus, filling nitrogen, reacting for 2-3 hours, drying at 130-170 degrees C, and crushing; and (2) preparation of lithium ion battery cathode comprising mixing lithium ion battery cathode material, conductive agent and binder at mass ratio of 9:1:2.5 into solvent, coating on current collector, and drying.
