| titleOfInvention | Preparation method of lithium iron phosphate |
| abstract | The invention provides a preparation method and system of lithium iron phosphate. The preparation system comprises a ball mill, a cyclone preheating device used for preheating a material through the afterheat of the system, a ball mill rotary kiln used for milling the preheated material in grades and dynamically sintering at the same time, and a cooler. The method comprises the following steps of: mixing ferric salt, lithium salt and phosphate in molar ratio of Fe: Li: P of (0.8-1.2): (0.8-1.2): 1; adding a solvent which is 2 to 5 times the total weight of the mixture; performing ball milling for 2 to 20 hours through the ball mill; dispersing to feed into the cyclone preheating device for preheating and predecomposition; transferring into the ball mill rotary kiln for sintering and milling in grades at the same time; and discharging and feeding the product meeting the particle size requirement into the cooler for cooling to reach the room temperature so as to obtain the finished lithium iron phosphate. The preparation method is a continuous full-dynamic sintering method, and the product prepared by such method is less in agglomeration, small in particle size, high in uniformity and relatively high in quality and stability of batches. |
