| titleOfInvention | A method for assisted synthesis of lithium iron phosphate cathode material without liquid solvent |
| abstract | The invention relates to the field of lithium iron phosphate synthesis, and discloses a method for assisted synthesis of lithium iron phosphate positive electrode material without a liquid solvent, comprising the following steps: mixing iron phosphate with a flow aid and anti-sticking agent, and performing crushing and depolymerization to obtain depolymerized lithium iron phosphate. The precursor; the flow-promoting anti-sticking agent includes component A and component B, and component A includes one or more of graphite, graphite fluoride, molybdenum disulfide, boron nitride and talc, and the component B includes one or more of magnesium stearate, lithium stearate, polyoxymethylene, polyimide, polyparaben and nylon; solid-state mixing of depolymerized precursors and other raw materials; sintering and crush. In the present invention, the component A and the component B with specific properties are compounded as a flow aid and anti-sticking agent, and are matched with iron phosphate, so that the lithium iron phosphate positive electrode material can be prepared by a solvent-free solid-phase method, and the process of removing the solvent can be avoided. At the same time as the uncontrollable factors generated, the uniformity of raw material mixing is improved, and the lithium-ion battery is given better performance. |
