Claim 15:
16. A solid electrolyte layer, comprising a crystallographically-oriented crystalline material comprising a halide material represented by (Li1−d−e, Nad, M′e)2Li1−z(Mek+)fX3+k*f−z, wherein:
−3≤z<3;
2≤k<6;
0≤f≤1;
−3≤z<3;
2≤k<6;
0≤f≤1;
0≤d≤1;
0≤e<1;
(d+e)>0; and
M′ consists of at least one of K, Rb, and C;
Me comprises a divalent metal element, a trivalent metal element, a tetravalent metal element, a pentavalent metal element, a hexavalent metal element, or any combination thereof;
X comprises a halogen; and
the halide material comprises at least two different cations,
wherein a crystallographic orientation of the crystallographically oriented crystalline material is in a direction of a thickness of the solid electrolyte layer, wherein an ionic conductivity in the crystallographic orientation is higher than an ionic conductivity in a different crystallographic orientation,
wherein the solid electrolyte layer further comprises:
a total content of simple metal halide of at most 2 wt % for a weight of the halide material, wherein the simple metal halide comprises alkali metal halide, rare earth halide, or any combination thereof;
at least one of electric charge neutral MexNk or MxN, wherein x is a valence of N and k is the valence of Me; or
any combination thereof.
