Lithium-sulfur batteries have gotten to be a hot inquire about subject due to their tall hypothetical particular capacity (1675 mAh g_^-1) and energy density (2600 Wh kg_{-1). Focal points such as plenteous sulfur assets, non-toxicity and natural invitingness moreover make lithium-sulfur batteries one of the foremost promising vitality capacity frameworks. In any case, the destitute electrical conductivity of sulfur, the "transporting" of polysulfide between anodes and the contrast in thickness between sulfur and its diminishment items are still issues that restrain its application. Related studies have appeared that move metal selenides have great electrical conductivity. Based on their polar characteristics, move metal selenides can quicken the energy of redox responses, smother carry impacts, and make strides the electrochemical execution of lithium-sulfur batteries. This paper mainly reviews the applications of move metal selenides in lithium-sulfur battery cathode materials and stomachs, and presents an viewpoint on long run investigate course and advancement drift of move metal selenides in lithium-sulfur battery applications.}
