ABSTRACT
In the era of ever-increasing demand for energy consumption, the need for efficient energy storage and delivery device is of paramount importance. A supercapacitor, owing to its quick charging time and very high power delivery, is among the most viable alternatives for energy storage systems. Carbon nanostructures in the past decade have become a significant substrate for the fabrication of electrodes for supercapacitors. The use of two-dimensional and one-dimensional carbon nanostructures such as graphene and carbon nanotubes is well known. The use of zero-dimensional carbon nanostructures in supercapacitors is very recent and warrants a discussion. This chapter discusses the synthesis and use of zero-dimensional carbon nanostructures for supercapacitors.
