PREPARATION METHOD FOR HIGH-PERFORMANCE LITHIUM IRON PHOSPHATE AND USE THEREOF
Disclosed are a preparation method for high-performance lithium iron phosphate and use thereof. The method comprises the following steps: dispersing a lithium salt into a solvent A, and adding an organic acid to adjust the pH to obtain a mixed solution; dispersing porous iron phosphate into a solvent B, and adding an organic carbon source to obtain a mixed slurry A; adding the mixed slurry A into the mixed solution; grinding the obtained slurry; adding a dispersing agent into the grinding material for stirring and dispersing to obtain a mixed slurry B; placing the mixed slurry B under the pressure of 100-1000 Pa for aging and drying; and sintering the obtained dry material in an inert atmosphere to obtain lithium iron phosphate.
