NOVELTY - Preparing carbon negative electrode material for lithium-ion battery involves adding the artificial graphite, organic silicon source and oxidation graphene to the mass ratio of 10:(1-5):(0.1-1.5), stirring for 10-30 hours to reaction kettle the precursor mixture; putting the precursor mixture obtained into a rubber mold uniformly and alternately placing with the metal lithium, putting into an isostatic pressing forming machine for pressing, the pressure is 90-150MPa to obtain the pressing block; sintering the pressing block obtained by discharging plasma sintering using nitrogen as protective gas, the temperature is 1500-2000degrees Celsius, the pressure is 10- 40Mpa, sintering time is 10-15 min, crushing and sieving to obtain the silicon carbon negative electrode material. USE - Method for preparing carbon negative electrode material for lithium-ion battery. ADVANTAGE - The method enables to effectively relieve the problem of silicon material and carbon material falling off and electrode pulverization caused by the volume change of the silicon negative electrode the circulation process.
