Advanced Materials for Energy Storage Devices

Increased energy consumption and global warming stimulate the development of various energy types which are clean, efficient, sustainable, and cheap. As a result, the storage of these different types of energy becomes a key issue. Energy storage is more important today than at any time in human history. From this perspective, numerous studies have been reported and advancement in both the fundamental and applied fields of energy storage devices has been achieved. The superior electrochemical properties, such as high energy density, fast charge-discharge rates, excellent cyclic stability, and specific capacitance of the devices are highly dependent on the chemical compositions and structures of the electrode and electrolyte materials. During recent decades, a significant amount of researches have been dedicated to enhancing the electrochemical performance of energy storage devices through the development of novel electrode and electrolyte materials. This chapter discusses the latest progress of various types of advanced anode, cathode, and electrolyte materials for supercapacitor, lithium-ion capacitor, lithium-ion battery, and sodium-ion battery. Moreover, major challenges to be tackled and future perspectives for these materials are also highlighted.
