NOVELTY - The method involves determining an iron phosphate lithium sample and a graphite sample. A ball-milling part and a mixing powder machine are connected with each other. Height of the ball-milling part is maintained about 3-20 cm. The ball-milling part is made of graphene material. Lithium particle is determined. Diameter of the lithium particle is maintained about 1-10 micron. A graphene nanometre sheet is fixed with the mixing powder machine. Phosphate lithium sample drying process is performed. The graphite sample is a mixture of alginate, cellulose sodium or polyacrylic acid solutions. USE - Iron phosphate lithium battery positive pole material preparing method. ADVANTAGE - The method enables realizing iron phosphate lithium battery positive pole material preparing process in a simple manner with wide range of applications.
