    摘要： In a method for manufacturing alkalimonofluorophosphate of general formaula M2PO3F (I), where M stands for the cation of a metal of the first main group of the periodic system, in particular potassium, a reaction mixture containing alkali metal cations M, phosphate, fluoride, particularly in the form of alkali hydroxyde, phosphoric acid and hydrofluoric acid, and water, the molar ratio of M:P:F being (2±0,1):(1±0.05):(1±0.1) and the molar ratio of water:P being at least 1:1, is heated to a temperature of 150 °C to 400 °C. Alkalimonofluorophosphate of general formula (I) occurs, with evaporation of water, as a reaction product, which is then isolated.

    摘要： The present invention relates to the field of sodium-ion battery technology, and specifically, to a method for preparing carbon-coated sodium iron fluorophosphate from waste lithium iron phosphate and the application thereof. The method for preparing carbon-coated sodium iron fluorophosphate from waste lithium iron phosphate includes: mixing a waste lithium iron phosphate material with an alkaline solution for reaction, followed by solid-liquid separation, to obtain an aluminum-containing filtrate and a lithium iron phosphate filter residue; mixing the lithium iron phosphate filter residue, aluminum chloride and sodium chloride uniformly, followed by vacuum calcination, to obtain a calcination material; and mixing the calcination material with at least one of a sodium source, an iron source and a phosphorus source uniformly to obtain a mixture to which a fluorine source, a carbon source and a solvent are added for uniformly mixing, followed by drying and calcination sequentially to obtain the carbon-coated sodium iron fluorophosphate. The method has the advantages of low costs, a high added value, a short process, and a high recovery rate, and the carbon-coated sodium iron fluorophosphate obtained from the method has excellent electrochemical performance.
