An inorganic compound for a Li-ion conductor includes an oxyhalide compound with a chemical composition of MOX where M is at least one of Al, Sc, La, and Y, and X is at least one of F, Cl, Br, and I. Also, the oxyhalide compound has a thermal decomposition start temperature of the oxyhalide compound is greater than a thermal decomposition start temperature of FeOCl and a conductivity that is general equal to or greater than a conductivity of the FeOCl.

Inorganic compounds for lithium-ion conductors

A method of synthesizing an inorganic precursor for an ionic conductor includes mixing at least one oxide of M with at least one halide of M, heating the mixture of the at least one oxide of M and the at least one halide of M and forming an MOX inorganic oxyhalide compound, and injecting defects in the MOX inorganic oxyhalide compound and forming a defect doped (MOX)' precursor for an ionic conductor. The element or component M is selected from at least one of Fe, Al, La, and Y, the at least one halide of M is selected from at least one of a fluoride of M, a chloride of M, a bromide of M, and an iodide of M, and the element or component X is at least one of F, Cl, Br, and I.

Inorganic precursors for ionic conductors

A lithium-ion conducting composite material includes a Li binary salt, a Li-ion conductor with a chemical composition of LiFeO(OH)Cl, and at least two of: a first inorganic compound with a chemical composition of (FeM1)O(OH)Cl; a second inorganic compound with a chemical composition of M2OX; and a defected doped inorganic compound with a chemical composition of (M3OX)'. The value of n is 1 or 2, x is greater than 0 and less than or equal to 0.25, and y is greater than or equal to 0 and less than or equal to 0.25. Also, M1 is at least one of Mg and Ca, M2 and M3 are each at least one of Fe, Al, Sc, La, and Y, and X is at least one of F, Cl, Br, and I.

Lithium-ion conducting composite material

An ionic conductor includes an inorganic oxychloride compound with a chemical composition of (FeM)O(OH)Clwhere M is selected from at least one of Mg and Ca, and x is greater than 0 and less than or equal to 0.25, y is greater than or equal to 0 and less than or equal to 0.25. The inorganic oxychloride compound has a thermal decomposition start temperature of about 410&#xb0; C. and x-ray diffraction peaks (2&#x3b8;) between about 20.79&#xb0; and about 22.79&#xb0;, between about 30.03&#xb0; and about 32.03&#xb0;, between about 39.47&#xb0; and about 41.47&#xb0;, and between about 76.44&#xb0; and about 78.44&#xb0;.
