Nanostructured materials for energy-related applications

Materials play a key role especially in the field of energy storage and conversion. Design of efficient and cost-effective materials for energy applications is of prime research focus. This chapter presents the recent trends in the energy-related applications of various carbon nanotubes (CNT) and their hybrid nanostructures. Development of CNT-based electrocatalysts for proton exchange membrane fuel cells and CNT-based electrodes for supercapacitors and Li-ion batteries are discussed.
