Polyaniline in various forms has been widely explored as an electrode material for supercapacitors due to its high theoretical charge storage capacity, facile-cost-effective synthesis, good mechanical strength and ultrafast charge transport. However, commercialization of such pristine forms is very much restricted by low solubilities, rapid agglomeration during device design accompanied by poor electrochemical life and fast environmental decomposition. The blending with nano-carbon materials, metal oxides and other competent materials, may result in high quality materials– “nanocomposites” with superior features is ideally fit for future generation energy storage devices. The present chapter deals with detailed discussions on designing, the fabrication of such binary and ternary nanocomposites, correlating their morphology with electrochemical behavior, so as to optimize their supercapacitive performances. Such an attempt would help to outline the present status and future aspects of these materials which will be of first-hand assistance especially to the beginners to this field of research.

Low Dielectric

Dielectric capacitors have been widely studied because their electrostatic storage capacity is enormous, and they can deliver the stored energy in a very short time. Relaxor ferroelectrics-based dielectric capacitors have gained tremendous importance for the efficient storage of electrical energy. Relaxor ferroelectrics possess low dielectric loss, low remanent polarization, high saturation polarization, and high breakdown strength, which are the main parameters for energy storage. This article focuses on a timely review of the energy storage performance of BiFeO3-based relaxor ferroelectrics in bulk ceramics, multilayers, and thin film forms. The article begins with a general introduction to various energy storage systems and the need for dielectric capacitors as energy storage devices. This is followed by a brief discussion on the mechanism of energy storage in capacitors, ferroelectrics, anti-ferroelectrics, and relaxor ferroelectrics as potential candidates for energy storage. The remainder of this article is devoted to reviewing the energy storage performance of bulk ceramics, multilayers, and thin films of BiFeO3-based relaxor ferroelectrics, along with a discussion of strategies to address some of the issues associated with their application as energy storage systems.
