Photonic crystal structures as a basis for a three-dimensionally interpenetrating electrochemical-cell system

Abstract

A novel interpenetrating electrode structure is synthesized by sequential assembly of nanostructured components throughout the interconnected macropores of an inverse opal carbon monolith. Separation of electrodes by a thin polymer electrolyte film prevents hard shorts and permits intercalation and shuttling of Li ions between electrodes (see figure and inside cover).
