摘要
Provided is a method for producing a lithium cobalt phosphate represented by the following general formula (1):LixCo1-yMyPO4 (1), wherein 0.8≤x≤1.2 and 0≤y≤0.5, and M represents one or two or more metal elements selected from the group consisting of Mg, Zn, Cu, Fe, Cr, Mn, Ni, Al, B, Na, K, F, Cl, Br, I, Ca, Sr, Ba, Ti, Zr, Hf, Nb, Ta, Y, Yb, Si, S, Mo, W, V, Bi, Te, Pb, Ag, Cd, In, Sn, Sb, Ga, Ge, La, Ce, Nd, Sm, Eu, Tb, Dy, and Ho; the method comprising: a first step of adding an organic acid and cobalt hydroxide to a water solvent, and then adding phosphoric acid and lithium hydroxide thereto to prepare an aqueous raw material slurry (1); a second step of wet-pulverizing the aqueous raw material slurry (1) with a media mill to obtain a slurry (2) containing a pulverized product of raw materials; a third step of spray-drying the slurry (2) containing the pulverized product of raw materials to obtain a reaction precursor; and a fourth step of firing the reaction precursor. According to the present invention, a single-phase lithium cobalt phosphate in X-ray diffraction analysis can be obtained by an industrially advantageous method.
