Abstract
A lithium ion conductive material has a composition formula of Li(OH)FClBr, where 1.8≤a≤2.3, b=a −c−1, 0<c≤0.30, 0<d<1, and includes an antiperovskite-type crystal phase. The lithium ion conductive material is manufactured, for example, by heating LiOH, LiF, LiCl, and LiBr at a temperature not lower than 250° C. and not higher than 600° C. for 0.1 hours or more while stirring them at a molar ratio of 1:X:Y:Z (where 0.03≤X≤0.3, 0.2≤Y<1.1, 0<Z<1) under an Ar gas atmosphere.
