1. An article, comprising:
a first electronically conductive solid substrate;
a second electronically conductive solid substrate; and
an ionically conductive and electronically insulating region between the first electronically conductive solid substrate and the second electronically conductive solid substrate, wherein the ionically conductive and electronically insulating region comprises a plurality of electronically insulating elongated nanostructures extending from the first electronically conductive solid substrate to the second electronically conductive solid substrate,
wherein the elongated nanostructures have aspect ratios of greater than or equal to 10, and
wherein the electronically insulating elongated nanostructures are ionically conductive.
