摘要： Disclosed are a method for preparing lithium iron manganese phosphate precursor and a method for preparing lithium iron manganese phosphate. The method for preparing lithium iron manganese phosphate precursor comprises the following steps: (1) preparing liquid material A and liquid material B, wherein the liquid material A is a mixed solution of manganese salt and iron salt, and the liquid material B is oxalic acid or phosphoric acid solution; (2) subjecting liquid material A and liquid material B to a co-precipitation reaction in a rotary packed bed (100) to obtain a first slurry; (3) washing and filtering the first slurry to obtain a filter cake; (4) mixing the filter cake with water, adding a carbon source, and stirring until uniform to obtain a second slurry; (5) homogenizing the second slurry; (6) drying the homogenized second slurry, to obtain the lithium iron manganese phosphate precursor. The particle size of the lithium iron manganese phosphate precursor prepared by the method is finer and more uniform than that of a precursor prepared by a traditional method using a reaction kettle, the preparation speed is increased, and the carbon coating is more uniform.

摘要： A system and method thereof are provided for multi-stage processing of one or more precursor compounds into a battery material. The system includes a mist generator, a drying chamber, one or more gas-solid separators, and one or more in-line reaction modules comprised of one or more gas-solid feeders, one or more gas-solid separators, and one or more reactors. Various gas-solid mixtures are formed within the internal plenums of the drying chamber, the gas-solid feeders, and the reactors. In addition, heated air or gas is served as the energy source within the processing system and as the gas source for forming the gas-solid mixtures to facilitate reaction rate and uniformity of the reactions therein. Precursor compounds are continuously delivered into the processing system and processed in-line through the internal plenums of the drying chamber and the reaction modules into final reaction particles useful as a battery material.
