Keeping in mind the various hurdles of components that are used in the traditional secondary electrochemical energy storage devices, the center of focus nowadays is on producing electrodes that are portable, lightweight, wearable, and mechanically flexible. A feasible solution to the problem stated above can be stemmed from crafting an electrode that helps us to circumvent the problems of the conventional components as well as such materials which offer more active sites and shorter diffusion paths for Li+ ions in rechargeable lithium-ion batteries. While TMDs have been widely studied for practical applications in lithium-ion batteries, most of them are concerned with MoS2 and WS2. With a narrower bandgap and lower electronic conductivity than MoS2, MoSe2 has been less investigated. By incorporating carbonaceous materials, the conductivity of this material can be improved, and the active sites can be increased as well. As polymeric precursor-derived silicon oxycarbide (SiOC) has been termed as an “all-rounder” material for various applications, their application in LIBs has also been reported to bring better cycling stability and rate capability by providing free carbons in the ceramic form. In this study, for the first time, we report the fabrication of a freestanding electrode material made with a small amount of two-dimensional MoSe2 along with SiOC fibermats. After characterizing the structure of the fibermat with microscopic techniques (such as SEM, TEM, and XPS) and spectroscopic techniques (such as Raman spectroscopy and FTIR) a lithium-ion half-cell was assembled using the material which showed improved cycling stability and rate capability.
