<P>PROBLEM TO BE SOLVED: To provide a positive electrode active material for a lithium battery, capable of materializing high discharge capacity, stable charge and discharge cycle characteristics, high filling performance, and a high output, its manufacturing method, and the lithium battery. <P>SOLUTION: This manufacturing method of a positive electrode active material for the lithium battery is a manufacturing method of Li<SB>x</SB>A<SB>y</SB>D<SB>z</SB>PO<SB>4</SB>(wherein, A is one kind selected from Co, Ni, Mn, Fe, Cu, and Cr, D is one or two or more kinds selected from Mg, Ca, Fe, Ni, Co, Mn, Zn, Ge, Cu, Cr, Ti, Sr, Ba, Sc, Y, Al, Ga, In, Si, B, and rare earth elements and is different from the A, 0 ≤ x < 2, 0 < y < 1.5, and 0 ≤ z < 1.5). A Li component, a P component, an A component, a D component, and an inorganic particulate are added in a solvent having water as a main component to make a solution, and then the solution is heated under pressurization to produce Li<SB>x</SB>A<SB>y</SB>D<SB>z</SB>PO<SB>4</SB>. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
