A method for making lithium iron phosphate is provided.In the method, a lithium ion source solution including lithium ions, a ferrous ion source solution including ferrous ions, and a phosphate-radical source solution including phosphate-radicals are provided. The lithium ion source solution, the ferrous ion source solution, and the phosphate-radical source solution are respectively formed by dissolving a lithium chemical compound, a ferrous chemical compound, and a phosphate-radical chemical compound in an organic solvent. The lithium ion source solution, the ferrous ion source solution, and the phosphate-radical source solution are mixed at a predetermined temperature in a range from about 90 ℃ to about 180 ℃ to form a mixed solution. The mixed solution is heated under the predetermined temperature to make the lithium ions, the ferrous ions, and the phosphate-radicals co-precipitate as the lithium iron phosphate. |
