<p>The present invention relates to a method for preparing a battery composite material, at least comprising: a step of providing phosphoric acid, iron powder, a carbon source and a first reactant, wherein the chemical formula of phosphoric acid is H3PO4, the chemical formula of the iron powder is Fe; a step of reacting phosphoric acid and the iron powder, to generate a first product; a step of calcinating the first product to generate a precursor, wherein the chemical formula of the precursor is Fe7(PO4)6; and a step of reacting the precursor and the first reactant and calcinating the reaction mixture, to generate a battery composite material. In the present invention, the preparation is performed without using a base compound, and the grinding time in the manufacturing process is reduced, thereby reducing the cost in time and money. At the same time, the efficacy of reducing the difficulty of the manufacturing process and operation of the production line is achieved.</p> |
