Abstract
Due to the increase in the use of renewable energy and its unsteady nature, energy storage and distribution system has been getting significant attention during the last two decades. To establish an efficient energy storage system, large capacity supercapacitors together with secondary batteries are essential. Numerous researchers have been trying to develop high performance supercapacitor electrode materials. As the EDLC-type supercapacitors showed limitations in energy density, composites of graphene, CNT, or carbon nano-onion (CNO)-based metal sulfides (or oxides) have been synthesized to achieve high performance of supercapacitors. Other sophisticated metal oxide materials such as MXene, metal organic framework (MOF), and perovskite as well as hydroxide materials such as layered double hydroxide (LDH) have also been studied. Also, three-dimensional hollow electrode structure has been getting attention as it provides a large surface area and large pores that allow electrolytes and charges penetrate freely. In this study, we introduce high-performance metal sulfide and oxide nanocomposite electrode materials and their fabrications for supercapacitor devices.
