Abstract
A lithium-ion conducting composite material includes a Li binary salt, a Li-ion conductor with a chemical composition of Li2−3x+y−zFexOy(OH)1−yCl1−z, and at least two of: a first inorganic compound with a chemical composition of (Fe1−xM1x)O1−y(OH)yCl1−x; 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.
