| description | The invention provides an iron phosphate precursor and a preparation method thereof, a lithium iron phosphate positive electrode material and a lithium ion battery, and relates to the technical field of lithium ion batteries. The preparation method of the iron phosphate precursor comprises the following steps: mixing iron ore, a phosphorus source and acid to obtain a mixed solution; and carrying out hydrothermal reaction on the mixed solution, carrying out solid-liquid separation, and then cleaning and drying a solid product to obtain the iron phosphate precursor. The invention further provides an iron phosphate precursor which comprises the hexagonal lamellar primary particles. According to the method, the iron phosphate precursor can be prepared from the iron ore which is low in price and wide in source through a simple process, the production cost is reduced, and the prepared iron phosphate is high in purity and suitable for further preparing lithium iron phosphate with excellent electrochemical performanc |
