Description

Technical Field

[0002] Lithium iron phosphate (LiFePO4) is a lithium-ion battery cathode material with the advantages of high energy density, long cycle life, good thermal stability and environmental friendliness. The preparation of lithium iron phosphate usually includes the following main steps: mixing ingredients, grinding, spray drying, sintering synthesis, crushing, sieving iron removal and packaging. The production principle of iron phosphate is to use ferrous sulfate, hydrogen peroxide, monoammonium phosphate and other raw materials, through solution preparation, ferrous impurity removal, oxidation synthesis, filter pressing washing, drying, crushing and other processes.

[0003] Raw materials such as iron phosphate, lithium carbonate, and glucose are mixed in a certain proportion to prepare a slurry. During the batching process, iron phosphate and lithium carbonate are first placed on the upper part of the silo, and the bottom of the packaging bag is cut by the internal cutter of the silo equipment, and the materials leak into the silo. The materials temporarily stored in the silo are weighed according to the formula ratio and put into the batching tank. Glucose is directly added to the batching tank. Finally, pure water is added to prepare the materials into a slurry, which is pumped into the sanding machine by an air pressure pump.

[0004] However, when mixing raw materials such as iron phosphate, lithium carbonate, and glucose, the slurry needs to be stirred evenly. However, when the powder and liquid are mixed, there is a possibility of agglomeration during the stirring process, so a long period of stirring and mixing is required, and the stirring efficiency is not high. Summary of the invention
