Chapter 8 - Ferrites in energy: limitations and perspectives

Abstract

The ferrites, a class of materials showing a wide range of applications in energy storage, generation and transport devices such as supercapacitors, batteries, solar cells, chemical and optical sensors and water splitting etc., demonstrate few shortcomings including conductivity and surface area which are the most important while tuning decisive properties of the electrode materials. The conductivity and surface area of the various ferrite electrode materials can be enhanced on combining them with highly conducting materials like polymers, graphene oxides, reduced graphene oxides, and carbonaceous materials which can improve the electrochemical performance of the ferrite/ferrite-based electrode materials in energy storage devices. These materials not only are promoting the electrochemical performance but also avail higher specific capacitance, prolonged cyclic stability, and ion diffusion rate. The cost-effective ternary ferrites are trustworthy electrode materials with excellent specific capacitance, long discharge time, and good conductivity. In this chapter, deficiencies of ferrite materials in addition to future perspectives are thoroughly discussed discussed.
