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.

水热法制备超级电容器用二元金属硫族化合物（MS@NS）

本研究对不同的二元过渡金属硒化物（BTMSe）进行了实验比较，以发现有前途的超级电容器（SCs）电极材料。研究人员目前正在研究硒基材料及其纳米结构在储能设备领域的潜力。虽然，有有限的研究检查的实用性，采用BTMSe作为电极材料。本文采用水热法制备了硒基材料MnSe、NbSe2及其纳米复合材料MnSe@NbSe2。超级电容器（SCs）具有优异的特性，特别是超过6000次循环的出色循环稳定性，比能量（58.72 Wh kg−1），比功率（281 Wh kg−1），比电容（Csp）在1 A g−1时为2079 F g−1。在材料合成方法上有一个重要的共识，在未来存储设备的新兴电容电极的电荷存储过程中有大量的新见解。图形抽象

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.
