Carbon nanostructures have become one of the most exciting and rapidly expanding research topics since the
discoveries of fullerene and carbon nanotubes. In particular, carbon nanotubes, graphene, and mesoporous carbons are the
most important classes of carbon nanostructures in terms of synthesis and practical applications. Due to their excellent
chemical, physical, mechanical, and electrical properties, carbon nanostructures have been considered as promising
candidate materials for energy devices. Therefore, it is important to summarize and review the previous research on
carbon nanomaterials in energy storage, conversion, and generation. Herein, the typical fabrication procedures for carbon
nanostructures, and the characteristics and performances of those carbon nanomaterials as major components in energy
devices are briefly described. The wet-type approaches to carbon nanomaterials are discussed extensively because the
chemical vapor deposition and template methods have already been reported frequently. In addition, recent research on the
improvement of batteries, capacitors, and solar cells will be concisely reviewed.
