ABSTRACT

Carbon nanomaterials have many advantages for energy storage because of their unique properties, including superior electrical and thermal conductivities, high chemical stability, good mechanical strength, relatively low cost, high surface area, and large pore volume combined with rational porous structure. Therefore, carbon nanomaterials and their composites have been considered as attractive materials for advanced sandwich-type energy storage devices, such as supercapacitors, lithium-ion batteries, lithium-sulfur batteries, lithium-oxygen batteries, and sodium-ion batteries. This chapter deals with the recent developments of carbon nanomaterials for applications in various energy-storage systems, with highlights on critical issues and challenges. The potential research directions and perspectives of carbon nanomaterials in fields related to energy storage are also proposed.
