Abstract

The present invention relates to a method for manufacturing lithium metal phosphate (LMP) having, as a precursor, crystalline iron phosphate having a (meta)strengite structure or metal-doped crystalline iron phosphate having a (meta)strengite structure, the method comprising the steps of: mixing a lithium raw material with crystalline iron phosphate in slurry phase or cake phase; and heat-treating the mixture. The method, by having a lithium (Li) raw material and a carbon (C) coating material mixed with crystalline iron phosphate in slurry phase or cake phase, allows elements Li, Fe, P and C to be homogeneously mixed, and then, by having the elements dried simultaneously, enables manufacturing of high-quality LMP. Therefore, the present invention is not only capable of providing convenience during the manufacturing process for lithium metal phosphate, but also capable of providing a lithium secondary battery positive electrode active material having excellent battery characteristics.
