Abstract:
This thesis endeavors to explore the potential of hybrid materials consisting of MoSe2/MWCNTS@PANI as electrode materials for supercapacitors. The primary focus lies in assessing their electrochemical performance, stability, and energy storage capabilities. By investigating synthesis methods, characterizing structural and morphological properties, and conducting extensive electrochemical analyses, this research aspires to provide a comprehensive understanding of the unique advantages and limitations associated with MoSe2/MWCNTS@PANI composites. The outcomes of this study are poised to make meaningful contributions to the advancement of electrode materials for high-performance supercapacitors. Furthermore, they offer valuable insights into the practical applications of these materials in energy storage systems, addressing the critical need for efficient and sustainable energy storage technologies.
To synthesize the PANI-MWCNTs/MoSe2 composite for electrochemical energy storage applications, a straightforward one-pot method was employed. This composite, composed of multiple MoSe2 nanospheres, PANI, and functionalized MWCNTs, exhibits remarkable properties when used as an electrode material in supercapacitors. Specifically, it demonstrates a high specific capacitance of 441 F/g at a scan rate of 20 Vs- and exceptional cycling stability, retaining 90% of its initial capacitance after 10,000 cycles. Notably, these samples showcase the ability to function effectively within a wide potential window (∆V=2V) when immersed in a 3M KOH solution, rendering them highly suitable candidates for integration into various electronic devices. This outstanding performance is largely attributed to the unique morphology of the composite, which significantly enhances its charge storage capacity. Collectively, these results underscore the potential of PANI@MWCNTs/MoSe2 as promising electrode materials for energy storage devices.
