METHOD FOR SYNTHESIZING LITHIUM IRON PHOSPHATE USING ANHYDROUS AMORPHOUS IRON PHOSPHATE

Disclosed is a method for synthesizing lithium iron phosphate using anhydrous amorphous iron phosphate. The method includes the following steps: mixing an anhydrous amorphous iron phosphate, a lithium source, an organic carbon source, and a liquid alcohol to obtain a wet mixture; grinding the wet mixture to obtain a slurry, and subjecting the slurry to spray drying to obtain a lithium iron phosphate precursor powder; and calcining the lithium iron phosphate precursor powder in a protective gas atmosphere to obtain an olivine lithium iron phosphate. An anhydrous amorphous iron phosphate is used as a raw material.
