Abstract:
1. A method for producing a lithium-containing composite oxide represented by general formula (1) below, the method comprising: a step of preparing a solution by dissolving a lithium source, an element M source, a phosphorus source, and an element X source that serve as source materials in a solvent, the phosphorus source being added after at least the element M source is dissolved, the step comprising a step of reacting an anhydride of a weak acid lithium salt as the lithium source with the element X source, and a step of reacting a halide of the element M as the element M source with the element X source; a step of gelating the resulting solution; and a step of calcining the resulting gel: (wherein M represents Fe and Zr; X represents Si; and 0<x≦2, 0.8≦y≦1.2, 0<z≦0.5).
