| titleOfInvention | Preparation method of lithium iron phosphate positive electrode active material |
| abstract | The invention provides a preparation method of a lithium iron phosphate positive active material, which comprises the following steps: dissolving an iron source, a phosphorus source, a lithium source and a polymer monomer in a solvent containing an oxidizing acid and/or a non-oxidizing acid to obtain a first mixed solution; when the first mixed solution contains oxidizing acid, adding a carbon source into the first mixed solution to naturally evaporate the solvent, and when the first mixed solution does not contain oxidizing acid, adding hydrogen peroxide after adding the carbon source into the first mixed solution to self-heat evaporate the solvent in the system; after the solvent is evaporated, obtaining a precursor of the positive active material; and sintering the precursor of the positive active material in the presence of a protective gas to obtain the lithium iron phosphate positive active material. The method has the advantages of simple process, low energy consumption, low requirement on equipment, low cost and suitability for large-scale industrial production and application, and the lithium iron phosphate anode active material prepared by the method has regular shape and high compaction density, and the battery prepared by the method has excellent electrochemical performance. |
