Abstract
A process of preparing a lithium metal phosphate includes contacting a water-soluble metal precursor, a water-insoluble metal precursor, and a phosphate precursor in an acidic aqueous medium; to form a reaction mixture; precipitating from the reaction mixture a metal phosphate; collecting the metal phosphate; combining the metal phosphate with a lithium precursor; and calcining the combined metal phosphate and lithium precursor at elevated temperature to form a lithium metal phosphate; wherein a mol ratio of water-soluble metal precursor to water-insoluble metal precursor is from 0.5:99.5 to 99.5:0.5.
