摘要：Disclosed is a method for manufacturing lithium metal phosphate (LMP) having,as a precursor, crystalline iron phosphate salt having a (meta)strengite structure or
metal-doped crystalline iron phosphate salt having a (meta)strengite structure, themethod comprising the steps of: mixing a lithium raw material with crystalline ironphosphate salt in a slurry phase or a cake phase; and heat-treating the mixture. Themethod, by mixing a lithium (Li) raw material and a carbon (C) coating material withcrystalline iron phosphate salt in a slurry phase or a cake phase, allows elements such asLi, Fe, P and C to be homogeneously mixed, and then, by having the elements driedsimultaneously, enables manufacturing of high-quality LMP. Therefore, the presentinvention is not only capable of providing convenience during the manufacturing processfor lithium metal phosphate, but also capable of providing a lithium secondary batterypositive electrode active material having excellent battery characteristics.
