NOVELTY - Graphene lithium power battery material comprises 3-5 pts. wt. acrylic acid, 100-150 pts. wt. lithium hydroxide, 400-500 pts. wt. ammonium ferrous phosphate, 30-40 pts. wt. carbon nanotubes, 7-9 pts. wt. etidronic acid 1-sintering aid, 2-4 pts. wt. aluminum stearate, 0.8-1 pt. wt. lanthanum nitrate and 1-2 pts. wt. sodium carbonate. USE - As a graphene lithium power battery material. ADVANTAGE - The material distributes evenly between graphene layers, and improves electrical cycles stability of battery material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the graphene lithium power battery material involving (a) adding carbon nanotubes to 30-40 times of nitric acid solution having a concentration of 96-98%, ultrasonically treating for 10-13 hours, filtering, washing resulting precipitate with water and dry at room temperature to obtain pretreated carbon nanotubes, (b) mixing acrylic acid and etidronic acid with pretreated carbon nanotubes, adding the mixture to 4-7 times of deionized water, heating and stirring at 60-65 degrees C for 1-2 hours to obtain a carbon nanotube dispersion, (c) adding lanthanum nitrate and sodium carbonate to the carbon nanotube dispersion, stirring for 40-60 minutes, suction filtering, washing the filter cake with water and drying at room temperature to obtain a premix and (d) mixing lithium hydroxide and premix, adding the mixture to 10-15 times of deionized water, stirring uniformly, adding sintering aid, transferring to a constant temperature water bath at 70-75 degrees C for 2-3 hours, cooling the material, adding ferrous ammonium phosphate to the material, stirring uniformly, suction filtering, washing the filter cake with water, mixing with aluminum stearate, transferring into a sintering furnace, passing argon gas and calcinating for 10-20 hours and cooling the material to obtain the product.
