With the depletion of fusel fuels and increase in demand for clean and sustainable energy, the importance given to energy storage devices has increased over the last decade. Supercapacitors are one of the most prominent energy storage devices due to their high power density, high specific capacitances, etc. Carbon-based materials, such as activated carbons and graphene, metal oxides, and conductive polymers, are mostly used as electrode materials in supercapacitors, and with the discovery of MXene a new two-dimensional (2D) material that has high conductivity, controllable thickness, and high surface area, it has become a popular material to research. Until then, there has been a lot of research investigating the electrochemical performance of MXenes in supercapacitors. This chapter contains several important studies on MXenes and MXene-based materials in supercapacitors and aims to present how MXene-based materials can be used to increase electrochemical performance.
