About this book

This book provides a much-needed, up-to-date overview of unary, binary and ternary bismuth-ferrite-based systems, with a focus on their properties, synthesis methods and applications as electrochemical supercapacitors. It introduces readers to the basic structure and properties of ferrites in general, focusing on the selection criteria for ferrite materials for electrochemical energy storage applications. Along with coverage of ferrite synthesis methods, it discusses bismuth-ferrite structures in unary, binary and mixed ferrite nanostructure systems, as well as future perspectives and limitations for using ferrites as electrochemical supercapacitors.

A valuable resource for beginners and advanced researchers working on similar topics, this book enables them to understand the core materials and electrochemical concepts behind bismuth-ferrite-based systems as energy storage materials.

1. Introduction

Abstract
This chapter describes the importance of energy storage devices and renewable energy global status and investment. There are different types of energy storage devices such as the battery, fuel cell, and supercapacitor of different operation mechanisms that are explained in short. In addition, the differences between the supercapacitors, fuel cells, and batteries, the advantages and disadvantages of supercapacitors, and their possible applications are also well-covered. Finally, the importance of bismuth ferrites in electrochemical studies has also been highlighted.

2. Electrochemical Supercapacitors: History, Types, Designing Processes, Operation Mechanisms, and Advantages and Disadvantages

Abstract
The perception of electrochemical supercapacitors (ESs) depended on the electric double-layer (EDL) existing at the interface between a conductor and its contacting electrolyte solution. The electric double-layer theory was the first proposed by Hermann von Helmholtz in 1853 and further developed by Gouy, Chapman, Grahame, and Stern. This chapter provides in depth information on the histroy of supercapacitors, their types, designing processes, operation mechanisms and advantages and disadvatnages.

3. Basics of Ferrites: Structures and Properties

Abstract
The word ‘ferrite’ is  derived from the Latin word ‘ferrum’ which means iron. The first type of magnetic material known to human was lodestone which is made up of the ore magnetite (Fe2O3). Ferrite is a ceramic material which is made by mixing iron oxide with metallic elements which  are electrically non-conducting or insulators.

4. Bismuth Ferrites: Synthesis Methods and Experimental Techniques

Abstract
This chapter is mainly concerned with the synthesis methods known for preparing bismuth ferrites either in powders or in thin-films. The experimental techniques employed for their characterizations are thoroughly explored. The synthesis methods used for obtaining ferrites of different structures and morphologies including hydrothermal, solvothermal, microwave, mechanothermal, seed-hydrothermal, sol-gel, chemical bath deposition, so-called coprecipitation or wet chemical synthesis, radio frequency, thermal plasma, spray pyrolysis, and electrodeposition technique etc., are throughly presented.

5. Electrochemical Supercapacitors of Bismuth Ferrites

Abstract
Nowadays, due to a fast-growing market for portable electronic devices such as mobile phones, laptops, notebook computers, and uninterruptible power supply systems and the development of hybrid electric vehicles, there has been an ever increasing and urgent demand for developing environmentally friendly high-power energy storage novel resources.

6. Limitations and Perspectives

Abstract
The utilization of energy from renewable sources depends on our ability to store the generated energy in electrochemical charge storage devices and to retrieve when needed. Thus, in recent times there is an impetus to the research on electric energy storage devices such as electrochemical supercapacitor and batteries. Thereby, this chapter highlights current issues related to electrocheical supercapacitors, ways to solve them, and future perspectives.
