Abstract

A lithium ion conductive material has a composition formula of Li(OH)FBr, where 1.8≤a≤2.3, b=a−c−1, 0.01≤c≤0.11, and includes an antiperovskite-type crystal phase. Preferably, the lithium ion conductive material further includes a layered antiperovskite-type crystal phase. More preferably, 0≤B/(A+B)≤0.2 is satisfied, where A is the peak intensity in the vicinity of 2θ=31.2° in the X-ray diffractometry using Cu-Kα ray and B is the peak intensity in the vicinity of 2θ=30.2°.
