Energy Conversion and Storage Devices

To meet the current emerging demands of the globe for sustainable progression in energy conversion and storage, there is a requirement for the expansion of advanced new materials that enhance efficacy in an indispensable manner. Materials are vital for fundamental improvements in energy sources to overcome the challenges of finite energy resources. The unique properties of nanomaterials, such as optical, electrical, mechanical, thermal, physical, and so on are widely used in energy devices to increase performance and boost the electrodes and electrolytes. Because of their extremely high superficial areas and enormous pore sizes, they can be used in energy transformation and storage applications. Further, these materials properties may enhance the execution of power, efficiency, stability, and life span in energy conservation and storage devices. This chapter discusses different energy forms such as chemical, electrical, mechanical, and thermal energies. Several materials used in energy devices, like flexible graphene, carbon nanotubes (CNTs), and nanoparticle composites are elaborated and discussed. The challenges and future prospects of several kinds of energy devices are also discussed.
