A Three‐Dimensional Carbon Nanotube/Graphene Sandwich and Its Application as Electrode in Supercapacitors

Abstract

Three-dimensional carbon nanotube/graphene sandwich structures with CNT pillars grown in between the graphene layers have been developed by chemical vapor deposition. The special structure endows the high-rate transportation of electrolyte ions and electrons throughout the electrode matrix, resulting in excellent electrochemical performance of this hybrid material.
