A method for preparing battery composite material, comprising the steps: providing phosphoric acid, a first metal source, a second metal source and water (S100); and the first metal source, the second metal source and the phosphoric acid reacting with water to generate a first product (S200); calcining the first product to generate a first precursor or a second precursor (S300), wherein the first precursor and the second precursor are solid solution containing a first metal and a second metal; and the first precursor and the second precursor reacting with a first reactant, then the reaction mixture being calcined to generate the battery composite material (S400). Therefore, the battery products have two stable redox charge and discharge platforms, and the stability and electrical performance of the products are effectively improved. |
