NOVELTY - A carbon/lithium stannate/graphene composite cathode material is prepared by mixing solution A and solution B in a volume ratio of 0.85:1 with major histocompatibility Complex /peptide complex and graphene suspension (0.1-0.4 mol/l). The solution A comprises stannic chloride pentahydrate, lithium hydroxide and deionized water in a mole ratio of 1:6:1.67. The solution B comprises ammonium bromide, citrimonium bromide as surface active agent and hexadecyl trimethyl, absolute ethyl alcohol and de-ionized water, where a mole ratio of hexadecyl trimethyl and absolute ethyl alcohol. USE - Carbon/lithium stannate/graphene composite cathode material. ADVANTAGE - The carbon/lithium stannate/graphene composite cathode material has larger carbon material capacity.
