ABSTRACT

Carbon-based materials are of interest in developing superca-

pacitors. Hitherto, variety of carbonaceous materials have been

investigated, developed, and commercialized as supercapacitor

electrodes. As power and energy densities have become imperative

for the development of supercapacitors, recently attention has

been focused to introduce carbon nanotubes (CNTs) as a three-

dimensional support for materials exhibiting pseudocapacitive

properties, for example, electrically conducting polymers (PANI, PPy,

PEDOT) or transition metal oxides, for example, MnO2. It has been

confirmed that CNTs play a vital role, forming conducting matrix

around the electrode-active materials forming nano-composite

electrodes. This chapter is devoted to studies centered on CNTs as

support for various pseudocapacitive materials and it explains the

merits of having CNTs as conductive additive support in the context

of enhancing the achievement of active capacitances.
