Nanocomposites of Carbon Nanotubes for Electrochemical Energy Storage Applications

Abstract

Carbon nanotubes are tube-shaped molecules that are composed of plunged sheets of one or more layers of carbon atoms arranged in a honeycomb hexagonal fashion. Because of their structural features and well-conducting networks they are extensively used in many devices viz. supercapacitors, smart textiles as well as other energy conversion devices. Because of the superior flexibility and stretchable nature carbon nanotubes show enhanced cyclic stability to be used as active electrode material. Moreover, carbon nanotubes serve as an excellent additive for conducting polymers, metal oxides, and graphene-based supercapacitors by providing the best route for the propagation of charge by drastically reducing the cell resistance. This chapter will explore the use of carbon nanotubes in supercapacitors, batteries, and fuel cells.
