1. A solid ion conductive layer, comprising:
a first phase extending continuously for at least a portion of the solid ion conductive layer, wherein the first phase comprises an ion conductive material comprising a halide-based material represented by formula M3−δ(Mek+)fX3−δ+*f, wherein −3≤δ<3, 0<f≤1, k is the valence of Me, 2≤k<6, M includes an alkali metal element including Li, Me includes a metal element that is different from M, and X includes a halogen; and
a second phase comprising an organic material comprising a binder material,
wherein the binder material comprises an HLB value of 0; and a Reactivity Value of 0; and
wherein the binder material comprises poly(vinylidene fluoride), polyisobutylene, or a combination thereof.
 
16. A composition, comprising a solid ion conductive material including a halide-based material represented by M3−δ(Mek+)fX3−δk*f, wherein −3≤δ<3, 0<f≤1, k is the valence of Me, 2≤k<6, M includes an alkali metal element including Li, Me includes a metal element that is different from M, and X includes a halogen and an organic material, wherein the organic material comprises polyisobutylene and a solvent having an HLB value of 0 and a Reactivity Value of 0.
