Abstract Scope Transition metal dichalcogenides (TMDs) are potential candidates for Li-ion (Li+) battery electrodes as they possess properties such as weak force between layers-of interest for ion-intercalation, and conversion chemistry with lithium-ions. But disadvantages such as capacity decay, and degradation reaction with electrolytes at low discharge potential make them vulnerable. As polymer-derived ceramics (PDCs) and PDC-based fibers specially silicon oxycarbide (SiOC) exhibit practicable energy storage capabilities towards Li+, SiOC functionalized TMDs can be beneficial in overcoming the disadvantages stated above. Herein, we report fabrication of SiOC functionalized TMD (MoSe2) in fibermat form which can be used as a freestanding electrode in Li-ion cells. Characterization of the structure of SiOC functionalized TMD fiber mats was carried out via electron microscopy and spectroscopic techniques (such as SEM, TEM, XPS, Raman Spectroscopy and FTIR). The electrochemical analysis of the electrodes showed improved cycle stability which are the signs of a promising Li-ion battery electrode.
