| titleOfInvention | Preparation method and application of lithium iron phosphate-carbon fiber composite cathode material |
| abstract | The invention provides a preparation method of a lithium iron phosphate-carbon fiber composite cathode material, which comprises the following steps: respectively acquiring a lithium source compound, a ferrous iron source compound and a phosphorus source compound according to the stoichiometric ratio of the lithium iron phosphate to be prepared, and adding a liquid dispersant; ball milling the acquired raw materials and drying; putting the dried products into a reaction chamber and introducing protective gas into the reaction chamber; and heating the reaction chamber to 300-900 DEG C, introducing carbon source gas, and pyrolyzing the carbon source gas at the temperature of 300-900 DEG C to prepare the lithium iron phosphate-carbon fiber composite cathode material. The invention also provides the lithium iron phosphate-carbon fiber composite cathode material prepared by the method. By the preparation method, carbon fibers are grown in situ from gas phase by pyrolyzing the organic carbon source and compounded with the lithium iron phosphate, thereby improving the dispersion degree of the carbon fibers in the lithium iron phosphate, and being widely applied in the fields of lithium ion batteries and the like. |
