NOVELTY - Anode material comprises 3-5 pts. wt. micron-sized oxysilylene powder, 1-2 pts. wt. spherical nano aluminum powder, 8-10 pts. wt. micro-nano-scale graphene oxide, and 10-20 pts. wt. polyvinyl chloride paste resin. USE - The anode material is useful for lithium ion battery (claimed). ADVANTAGE - The method: solves the problem that the pure silicon material has a very significant volume expansion (volume expansion rate more than 300%) in the process of high lithium insertion, and reduces cycle performance of technical problem. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing anode material comprising (i) providing 3-5 parts of micron-sized oxysilylene powder in an argon-filled glove box, and 1-2 pts. wt. spherical nano-aluminum powder, uniformly mixing in an argon-filled glove box, placing in an 80 ml stainless steel ball mill container with 15 counts of 10mm stainless steel balls embedded in the container, sealing with O-rings, then removing the glove operation box, adding on the ball mill, adjusting the ball mill speed to 400 revolutions/minute, where the each ball mill interval is 5-30 minutes, and ball milling time is 15 hours, (ii) sealing ball milling product and 8-10 pts. wt. micro-nano-scale graphene oxide in a glove box, and then ball milling at 450 revolutions/minute for 1-2 hours, (iii) adding the product of the secondary ball mill to 2.5 mol/l of excess hydrochloric acid, stirring for 2-4 hours, filtering, washing repeatedly with deionized water to pH of 7, drying under vacuum at 133 Pa and temperature at 100-130 degrees C for 2-4 hours to obtain porous silicon-nano aluminum-graphene oxide complex material, (iv) adding 10-20 pts. wt. polyvinyl chloride paste resin to 30-50 pts. wt. tetrahydrofuran, and completely dissolving the polyvinyl chloride to obtain a carbon solution, and (v) adding the porous silicon-nano aluminum-graphene oxide complex material to the carbon solution, stirring and uniformly mixing the powder and the solution using an ultrasonic dispersing device, after 5 hours, slightly heating the solvent while stirring constantly, volatilizing the solvent, transferring the mixture obtained into a quartz tube reaction device, where the device has an emotional atmosphere for protection, and the protective atmosphere is argon which does not participate in the reaction, then transferring the quartz reaction device to a high temperature furnace, carrying out the entire reaction process in an inert atmosphere, raising the temperature at a temperature increase rate of 5 degrees C/minutes, where the organic precursor is pyrolyzed and carbonized, carrying out the reaction at a temperature of 900 degrees C for 2-4 hours, completing the reaction, naturally cooling reaction system, pulverizing the complex material in an agate mortar, sieving to obtain a complex powder with a particle diameter of less than or equal to 74 um to obtain a anode material for a lithium ion battery.
