<p>A production method for a positive electrode active matter used in a non-aqueous electrolytic battery, comprising, when an positive electrode active matter, represented by a composition LixFe1-yMyPO4 (M is at least one kind out of Mn, Cr, Co, Cu, Ni, V, Mo, Ti, Zn, Al, Ga, Mg, B, Nb and 0.05≤ x≤1.2, 0≤y<0.8), is to be synthesized, the step of mixing at least Fe3(PO4)2·nH2O (n; hydration number of 0-8) with Li3PO4, and the step of firing the mixed raw material obtained in the mixing step, wherein the half width of the maximum diffraction peak, at X-ray diffraction using CuKα-ray, of the mixed raw material is up to 1.0°.</p> |
