Abstract

Supercapacitors are the electrochemical devices used to store and release energy via reversible adsorption and desorption of ions at the interface of active material and electrolyte interface. This energy storage device achieved high popularity due to its superior storage capability, better cyclic performance, high power density, and eco-friendly nature. Nanomaterials have been the subject of extensive research to develop low-cost, highly efficient, and stable electrodes. Ceramic materials exhibit the potential to be employed as supercapacitor electrode materials. On the other hand, the low specific surface area and low surface activity of ceramic materials significantly limit the performance of supercapacitors. The fundamental for knowledge of ceramics, the optimization approach, and the recent research in this field are critical for enabling superior electrical conductivity and good electron transportation properties and achieving economically practical ceramic electrodes in industry. This chapter discusses various advances in ceramic-based supercapacitor electrodes, mainly metal oxides, multi-elemental oxides, metal sulphides, and other unique ceramics (MXene), as well as multilayered ceramics, have been discussed. Additionally, the current challenges, as well as the perspective of ceramic-based ...
