1. A method for producing a multi-phase electrolyte film, the method comprising:
providing a mixture comprising
a lithium source, and
one or more metal oxide precursors comprising a nitrate or acetate of one or more of La, Zr, Hf, Si, Ti, Ca, Mg, Y, Ta, Al, Ce, Ta, Ga, Nd, or Dy;
spraying the mixture onto a solid substrate at a temperature of 150 to 500° C. to provide the multi-phase electrolyte film comprising
a first phase comprising a metal oxide, wherein the oxide is amorphous, crystalline, or a glass, and
a second phase comprising a lithium salt having a decomposition temperature in air of greater than 200° C. or a lithium halide,
wherein the second phase is dispersed in the first phase and has an average particle size of 5 to 200 nanometers.
