1. An energy storage device comprising a cathode region, the cathode region comprising:
an active material region comprising an active material that expands or contracts from a first volume to a second volume during a period of charge and discharge;
a catholyte material spatially confined in spatial regions not occupied by the active material region, wherein the catholyte material comprises:
a lithium element;
a phosphorous element;
a sulfur element;
a silicon element;
a tin element; and
an oxygen element;
wherein the catholyte material is characterized by a primary CuKa XRD peak at 2q=30°±1°, 2 q=33°±1°, or 2 q=43°±1°.
