Lithium-sulfur (Li-S) battery is one of the most promising candidate for the next-generation rechargeable cell. In order to control the shuttle effect of dissolution lithium polysulfides (LIPSs), the chemical interactions between sulfur host and LIPSs on the performance of Li-S batteries has recently been highlighted. Herein, a facile strategy is proposed, which produces graphene oxide (GO) as an anchor to restrain LIPSs in Li-S batteries via chemical confinement by strong bonding interaction between GO and Li<sub>2</sub>S<sub>6</sub>. X-ray diffraction (XRD), Raman analysis & Scanning electron microscopy (SEM) of prepared composite material was done to study structural and morphological properties. Electrochemical performance of GO-S composite cathodes using LiTFSI electrolyte was studied by galvanostatic charge-discharge at various c-rates as well as via cyclic voltammetry & EIS measurements. The detailed results of the study will be discussed during the presentation of meeting.
