Recent advances in biomass‐derived carbon, mesoporous materials, and transition metal nitrides as new electrode materials for supercapacitor: A short review

Abstract

A suitable electrode or active material is one of the promising ways to boost supercapacitors' efficiency. The right properties of the electrode materials will enhance the performance of the supercapacitors. New electrode materials such as biomass-derived carbon, mesoporous materials, and transition metal nitrides have been studied as potential substitutes for the most common electrode material, activated carbon. This review discusses the recent (5 years) progress of the electrode materials in supercapacitors compiling the literature from 2016 to 2020. The overview of design (structures), recent developments, and challenges of the new electrode materials are presented in this review with considerations on their electrochemical performance in supercapacitors.

Two dimensional layered nickel cobaltite nanosheets as an efficient electrode material for high‐performance hybrid supercapacitor

“…the energy density of the SCs through effective win-win strategies to address the future energy demands. [10][11][12] Therefore, engineering hybrid SCs (HSCs) comprising of a faradaic battery-type material (energy source) and a capacitive-type material (power source) with a wide operating voltage window to explore advanced SCs. [13][14][15] However, the overall performance of the efficient HSCs is primarily depending on the electrochemical properties of the battery-type electrode material.…”

A Review on the Conventional Capacitors, Supercapacitors, and Emerging Hybrid Ion Capacitors: Past, Present, and Future

“…[ 18 ] Meanwhile, some emerging electrode materials including Mxene, transition‐metal dichalcogenides (TMDs), and metal nitride/phosphide are also being extensively studied. [ 19,20 ] Certainly, the improvement of electrode materials is still in progress, including element doping, defect construction, and composites. Throughout the history of the development of EES equipment, it is inseparable from the development of electrode materials.…”

“…Composite materials are designed to achieve functional capabilities beyond the limits of each property such as energy density and lifetime. The production of new materials is essential to develop and improve power transmission and storage systems to meet the extreme energy needs of the growing low carbon economy [15][16][17]. Mesoporous materials have the potential to store high charges in energy storage owing to extensive surface area and pores.…”
