| titleOfInvention | Lithium iron manganese phosphate composite material and preparation method thereof, and secondary battery |
| abstract | The application belongs to the technical field of batteries, and in particular relates to a lithium iron manganese phosphate composite material and a preparation method, and a secondary battery. Wherein, the preparation method of the carbon-coated lithium iron manganese phosphate composite material comprises the steps of: separately obtaining lithium iron manganese phosphate recycled material, conductive agent recycled material and fluorine-containing recycled material; After the precursor is made; the precursor is sintered, and then mixed with the conductive agent recycled material and the fluorine-containing recycled material and then sintered to obtain a carbon-coated lithium iron manganese phosphate composite material with a core-shell structure; including iron manganese phosphate Lithium core, lithium iron phosphate interlayer, and carbon outer shell; doped with fluorine element along the radial gradient of the composite. In the method of the present application, the recycled material in the waste battery is used as the raw material, and the recycled material can be further purified and utilized in the preparation process, the recycling process is simplified, the recycling cost is reduced, and the prepared carbon-coated lithium iron manganese phosphate composite material has excellent electrochemical performance and structural stability. |
