摘　　要：锂硫电池被认为是最有发展潜力的新型多电子反应的二次电池体系之一.单质硫与锂反应的理论比容量为1675 mA h g?1,质量比能量达2600 W h kg?1,远远高于现行的传统锂离子二次电池材料.同时硫又具有来源丰富、环境友好等优点.然而,仍然有许多问题制约了锂硫电池的发展与广泛应用.本文综述了近年来锂硫电池正极材料的研究进展.Li-S batteries have long been considered as one of the most potential candidates of novel multi-electron reaction system. Given the complete reaction of Li with S to form Li2S, Li-S batteries exhibit a theoretical specific capacity of 1675 mA h g-1 and energy density of -2600 W b kg l, which are much higher than those of state-of-the-art Li-ion batteries. In addition, S is naturally abundant with low environmental impact. However, wide applications of Li-S battery are hindered by many inherent problems. Here we review the recent advances in the cathode materials for high-specific-energy Li-S batteries.
