NOVELTY - A composite positive pole material preparation method involves preparing nickel-cobalt-manganese precursor by utilizing nickel, cobalt, manganese as soluble salt of nickel, cobalt, manganese source, utilizing ammonium salt as complexing agent, polyvinyl alcohol or glutin as water soluble dispersant, adding complexing agent in the precipitator solution and adding dispersing agent to obtain precursor. The obtained solution is added to a reaction kettle, followed by stirring mixture, reacting and sintering resultant material to form lithium-nickel-cobalt-manganese oxide composite anode material.    USE - Method for preparing composite positive pole material that is utilized for manufacturing lithium ion battery.    ADVANTAGE - The method enables preparing composite positive pole material in a simple and inexpensive manner.    DETAILED DESCRIPTION - A composite positive pole material preparation method involves preparing nickel-cobalt-manganese precursor by utilizing nickel, cobalt, manganese as soluble salt of nickel, cobalt, manganese source, utilizing ammonia water or ammonium salt as complexing agent, polyvinyl alcohol, polyethylene glycol, methyl cellulose or glutin as water soluble dispersant, adding complexing agent in the precipitator solution and adding water-soluble dispersing agent to obtain precursor. The obtained solution is added to a reaction kettle by stirring under inert gas at a flow speed of 300-500ml/minute, stirring speed 200-300 rpm, reaction temperature of 45-85 degrees C, maintaining pH value at 8-13, continuously reacting for 24-48 hours, sintering resultant material to form lithium-nickel-cobalt-manganese oxide composite anode material. The material is subjected to solid-liquid separation process, followed by washing separated solid material till the PH value reaches 7-8, baking at 120-150 degrees C in an oven for 10-15 hours and drying to obtain nickel-cobalt-manganese precursor. The nickel-cobalt-manganese precursor is mixed with lithium source in a high speed mixer, putting in a sintering furnace to sinter at 5-20 degrees C for 750-1000 hours, cooling naturally in the furnace, performing air stream crushing by jet mill to form precursor and lithium source of layered lithium cobalt oxide, sintering resultant product in a furnace at 500-850 degrees C for 5-15 hours to obtain layered lithium cobalt oxide burning product and layered nickel-cobalt-manganese lithium primary burning product, The burning product and layered nickel-cobalt-manganese lithium primary burning product are added into a high speed mixing machine, followed by putting in the sintering furnace to sinter at 5-10 degrees C for 750-1000 hours, cooling naturally with the furnace to composite positive electrode material.
