1. A solid-state electrolyte structure, comprising:

a substrate of a first ion-conducting material and having a first surface, wherein the first ion-conducting material is a first solid-state ion-conducting electrolyte material; and

a non-planar first ordered porous microstructure disposed on a first surface of the substrate, the first ordered porous microstructure comprising a second ion-conducting material, and the second ion-conducting material is a solid-state, ion-conducting electrolyte material; and

wherein the first ordered porous microstructure comprises a plurality of columns arranged in a two-dimensional array.
