MXenes based 2D nanostructures for supercapacitors

Abstract

A supercapacitor is made up of three parts: separator, electrolyte, and electrodes. A supercapacitor's performance depends on electrodes with high porosity, chemical stability, and low electrical resistivity. MXenes are getting a lot of attention because of their high electrical conductivity, good mechanical properties, and Faraday pseudocapacitive charge storage mechanism. They are being used in supercapacitor applications. MXenes electrochemical characteristics are very advantageous for energy storage applications. There are three different mechanisms for supercapacitors, which will be discussed completely in this chapter. Furthermore, MXene performance can be increased by modifying the surface groups, interlayer structures, electrode morphology, or by manufacturing a composite with an additional functional material. Manufacture of the MXene electrode for testing and analysis is a vital step in getting a supercapacitor with good performance. Choosing a good blend of materials to accompany MXene is also a vital step. It's hard to find anything else like MXenes when it comes to appealing and unique properties like high electronic conductivity, tunable layer structure, and chemistry.
