    摘要:

    锂硫电池因较高的理论比容量(1675 mAh g-1)和能量密度(2600 Wh kg-1)成为研究的热点。硫资源丰富,无毒和环境友好等优势也使锂硫电池成为最有前途的储能体系之一。然而,仍然有硫的导电性差、多硫化物在电极之间来回“穿梭”和硫与其还原产物密度差异等问题制约其应用化发展。相关研究表明,过渡金属硒化物具有良好的导电性。基于其极性特征,过渡金属硒化物可以加速氧化还原反应动力学,抑制穿梭效应,改善锂硫电池的电化学性能。本文主要综述了过渡金属硒化物在锂硫电池正极材料以及隔膜等方面的应用,并且对过渡金属硒化物在锂硫电池应用的未来研究方向和发展趋势提出展望。

    Abstract:

    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.
