NOVELTY - Preparation of anode material of lithium ion battery comprises adding 0.5 wt.% graphene into 20-100 wt.% alcohol solution, ultrasonically oscillating, monodispersing, high-speed shearing emulsification homogenizing, adding 95-99.9 wt.% positive electrode active material powder, ball-milling using zirconia balls, mechanically mixing to obtain mixed slurry, drying in oven, crushing and sieving. The positive electrode active material powder is lithium iron phosphate, lithium cobaltate, lithium manganate, lithium nickel cobalt manganate and lithium nickel cobalt aluminate. USE - Method for preparing anode material of lithium ion battery (claimed).
