  "textContent": "The invention belongs to the field of battery material recovery, and discloses a preparation method and application of heterosite phosphate. The method comprises the following steps: mixing lithium iron phosphate with a solvent, adding an acid solution, and adjusting the pH to obtain an acidic lithium iron phosphate liquid; adding a transition metal additive to the acidic lithium iron phosphate liquid, and performing leaching in an intensifying micro-environment, followed by filtrating to obtain heterosite iron phosphate and a lithium-rich solution. The leaching rate of lithium in the leaching solution reaches 90.5-99.9%, and both of the iron and phosphorus content in the leaching solution are less than 0.1 ppm; the recovered heterosite iron phosphate has a purity of 99.9%, and the recovery rate of the heterosite iron phosphate is 99.3%.",
