Claim 19:
20. A method for making an electrolyte, comprising
providing an inorganic material, wherein the inorganic material has a particle size of about 50 nm to about 500 nm,
wherein the inorganic material is a solid state electrolyte selected from

a sulfide electrolyte characterized by the formula:

LiaSibSncPdSeOf, wherein 2≤a≤8,b+c=1,0.5≤d≤2.5,4≤e≤12, and 0<f≤10;

providing an organic material having a lithium conductivity of less than 10−8 S/cm at 80° C.;
mixing the inorganic and organic material to form a mixture;
casting the mixture; and polymerizing the organic material; wherein the method optionally comprises adding a polymer binder;
wherein the electrolyte comprises an inorganic material embedded in an organic material; wherein the inorganic material comprises particles of inorganic material which form a percolation network for lithium ion conduction through the electrolyte; and
wherein the inorganic material comprises necked-particles of inorganic material.
