Claim:
1. A method for fabricating a solid-state supercapacitor comprising: providing a first electrode comprising a first conductive supporting structure and a first array of conductive quasi-one-dimensional structures that extend from the first conductive supporting structure; providing a second electrode comprising a second conductive supporting structure and a second array of conductive quasi-one-dimensional structures that extend from the second conductive supporting structure; combining a matrix precursor and a hydrolysis precursor to form a sol; combining the sol and an ionic liquid electrolyte to form pre-ionogel before the sol hardens into a solid; positioning at least a first portion of the pre-ionogel between the first electrode and the second electrode; and supporting the first portion of the pre-ionogel until the pre-ionogel hardens into ionogel, which is a solid, thereby forming a solid-state ionogel structure that fills voids within and between the first array of conductive quasi-one-dimensional structures and the second array of conductive quasi-one-dimensional structures.
