Synthesis and Characterization of Mo2TiC2Tx MXene and Composites for Energy Storage Applications

Abstract

Exploring new novel and modified materials is very much crucial for promoting supercapacitor development in present-day electronics. MXene has been very prominent among various novel materials owing to its huge potential for energy storage applications. In this study, I have reported a detailed procedure for the etching and delamination of MXene and procedure for the composite formation with MWCNTs which shoes an outstanding capacitance of 1740 Fg-1 at 5 mVs-1 which makes it a suitable for supercapacitor electrode applications. Also provided an easy and versatile approach is adopted to prepare nickel metal ion (Ni) intercalated Mo2TiC2Tx MXene free-standing film-based electrode for binder-free flexible supercapacitor using the electrostatic self-assembly synthesis approach. As a result, an increase in the c-lattice parameter (c-Lp) due to intercalation is observed. Ni-Mo2TiC2Tx expresses an outstanding electrochemical performance with the gravimetric capacitance of 682 F g-1 at the scan rate of 5 mV s-1. Moreover, the synthesized binderfree Ni-Mo2TiC2Tx electrode possesses an excellent energy density of 59.77 W h Kg-1 at 0.1 Ag-1. This study provides insight into MXene structure modification for enhanced electrochemical performance with ultra-high capacity and opens doors to new ways of material tuning for energy storage applications.
