| titleOfInvention | Method for microwave synthesis of lithium iron phosphate material |
| abstract | The present invention relates to a method for the microwave synthesis of a lithium iron phosphate material, and specifically a method for the microwave synthesis of a lithium iron phosphate material using a waste battery is disclosed, the method specifically involving the following steps: (1) selecting a waste lithium iron phosphate battery, discharging same and then disassembling same to obtain a positive electrode sheet; (2) calcining the positive electrode sheet obtained in step (1) at 300-500°C for 1-10 h, taking same out when the temperature decreases to room temperature, mechanically vibrating the positive electrode sheet to make lithium iron phosphate fall off a current collector aluminum foil to obtain lithium iron phosphate powder; and (3) mixing the lithium iron phosphate powder, a lithium source, an iron source, a phosphorus source and a carbon source, ball milling same, then subjecting same to a microwave treatment for 10-100 s, and repeating the ball milling and microwave treatment steps until lithium iron phosphate particles are obtained. The process of the present invention is simple in operation, easy to control in process, lower in energy consumption, environmentally friendly, and does not produce secondary pollutants. Furthermore, the repaired lithium iron phosphate material can be reused for producing a lithium ion battery. |
