Abstract

This work conducts an experimental comparison of various binary transition metal selenides (BTMSe’s) to discover promising materials for supercapacitor (SCs) electrodes. Researchers are currently investigating the potential of selenide-based materials and their nanostructures in the realm of energy storage devices. Although, there is limited research examining the practicality of employing BTMSe’s as electrode materials. Herein, selenide-based materials such as MnSe, NbSe₂ and their nanocomposite MnSe@NbSe₂ were synthesized via the hydrothermal technique. Supercapacitors (SCs) with exceptional characteristics were observed, notably outstanding cycling stability exceeding 6000th cycle, specific energy (58.72 Wh kg⁻¹), specific power (281 Wh kg⁻¹), and specific capacitance (C_sp) of 2079 F g⁻¹ at 1 A g⁻¹, as indicated by thorough analysis. There is a significant consensus in material synthesis methods and a plethora of new insights into the charge-storage process in emerging capacitive electrodes for future storage devices.

期刊介绍： The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
