11.1 Introduction

Energy is one of the most significant latest topics of concern for the world. The con-
sumption of usual energy sources such as the wind, wave, and solar energy has to turn
out to be more and more essential due to retreating of fossil fuel reserves and the irrev-
ocable difficult impact on the atmosphere by smoldering of fossil fuels. Energy stor-
age space significance is not only for the directive of a variable power creation but
also, on a minor scale, for electronic devices and transport. Battery, energy cells,
and supercapacitors (also known as electrochemical capacitors, electrochemical
supercapacitors, or ultracapacitors) are electrochemical storage space machines that
are able to store charge throughout dissimilar mechanism. Supercapacitors, transi-
tional force, and energy source, among dielectric capacitors and batteries, have
emerged as essential energy storage equipment due to superior power deliverance,
high cyclability, and elongated existence point in time [1–3]. Supercapacitors cur-
rently filled the gap between batteries and electrostatic capacitors. Applications of
supercapacitors in automobile industry provide a maintenance-free, eco-friendly
power source, increased life of existing energy sources, large environmental working
range, efficient regenerative braking, increased scope of the stop and start technology,
power buffer in an electric drivetrain, and reduced weight and volume of energy stor-
age devices. Supercapacitors are too environmentally friendly than a battery. They do
not restrain perilous material like lead and are normally trouble-free to dispose of [4].
Nanocomposites consist of matrix of diverse material, which can exist as polymer,
metal, or ceramic and to which is added the charge, for example, multiwalled carbon
nanotubes, activated carbon, reduced grapheme oxide, natural clays, and graphene-
like materials that give new property to the substance, which helps in a particular
application. Among these types, polymeric ones have proved to be the most resource-
ful for their function in many research fields like engineering, construction, optoelec-
tronics, drugs, and ecological remediation, in specific removing water pollutant.
