Abstract

Transition metal carbides/nitrides and transition metal carbonitrides are collectively known as MXenes. Among the various MXenes available to date, titanium carbide (Ti3C2Tx) MXene is the most explored material due to its unique characteristics such as large surface area, good electronic conductivity, easy processability, etc. to name a few. Herein, we report the synthesis and characterizations of supercapacitor electrode comprising of Ti3C2Tx MXene nanosheets. The Ti3C2Tx MXene-based supercapacitor electrode synthesized via slurry coating followed by drop casting procedure. The electrochemical performances of the Ti3C2Tx MXene-based supercapacitor electrode are examined in a three-electrode cell set-up using characterization techniques such as electrochemical impedance spectroscopy and cyclic voltammetry. The Ti3C2Tx MXene-based supercapacitor electrode delivers a specific capacitance of 108.6 F/g at a scan rate of 5 mV/s. The electrochemical stability of the Ti3C2Tx MXene-based supercapacitor is examined for 2000 continuous cycles and exhibits a 100% capacitance retention even after the cycling study.
