Abstract
It is necessary to investigate effective energy storage devices that can fulfill the requirements of short-term and long-term durable energy outputs. Here, we report a simple one-pot hydrothermal technique through which to fabricate the MoS(2)/Te nanocomposite to be used as an effective electrode material for high-performance supercapacitors. Comprehensive characterization of the as-fabricated nanomaterial was performed using FESEM, HRTEM, XRD, FTIR, XPS, etc., as well as electrochemical characterizations. The electrochemical characterization of the as-fabricated nanocomposite electrode material showed a high specific capacitance of 402.53 F g(-1) from a galvanostatic charge-discharge (GCD) profile conducted at 1 A g(-1) current density. The electrode material also showed significant rate performance with high cyclic stability reaching up to 92.30% under 4000 cycles of galvanostatic charge-discharge profile at a current density of 10 A g(-1). The highly encouraging results obtained using this simple synthetic approach demonstrate that the hetero-structured nanocomposite of MoS(2)/Te electrode material could serve as a promising composite to use in effective supercapacitors or energy storage devices.
