| titleOfInvention | A method for preparing prelithiation agent by using waste lithium iron phosphate cathode material |
| abstract | The invention discloses a method for preparing a prelithiation agent by using waste lithium iron phosphate positive electrode material. The method for preparing the prelithiation agent Li 5 FeO 4 by using the waste lithium iron phosphate positive electrode material in the present invention comprises the following steps: mixing the waste lithium iron phosphate positive electrode material with the lithium source and then roasting, and obtaining the prelithiation agent after the roasting. The method of the invention can effectively recover Li, Fe and P elements in waste lithium iron phosphate, wherein Li and Fe are recovered in the form of prelithiation agent Li 5 FeO 4 , and P element is recovered in the form of occurrence of phosphoric acid. The whole-component and high-value recycling and reuse of waste lithium iron phosphate; waste lithium iron phosphate can be used as a good iron source and lithium source for synthesizing prelithiation agents, and the positive electrode material after multiple charge and discharge increases the material reaction. In the case of only supplementing the lithium source, the efficient synthesis of high-purity prelithiation agent Li 5 FeO 4 can be achieved at a lower calcination temperature and a shorter calcination time. |
