Carbon Nanotube/Graphene Hybrids for Energy Storage Applications

Abstract

Energy demand has become a very serious issue in the 21st century. Nanomaterials with controlled aspect ratio and composition can provide options for developing electrical storage devices like batteries and capacitors. This chapter deals with carbon nanotube/graphene hybrids for energy storage applications. An overview of carbon nanotube/graphene hybrids, their characteristics, and synthetic strategies are incorporated in the first half. Later use of CNT–graphene hybrids in fuel cells as supercapaci-tors and as hybrids for solar cells was also reviewed in this chapter. The hybrid material shows a good synergistic effect which will give improved performance.
