摘要
单质硫具有高理论比容量、丰富的储量、低成本和环境友好的特点,由硫正极和金属锂负极组成的锂硫电池能量密度可以达到1000 Wh/kg以上.然而,硫的绝缘性、穿梭效应和充放电过程中的体积剧变等限制了锂硫电池的应用.要同时解决这3个问题,合理的硫载体材料设计是关键.结合近年来的相关文献报道,综述锂硫电池硫载体材料及其相应的电化学性能,展望硫载体材料的发展趋势.
The advantages of sulfur include high theoretical specific capacity,abundant reserves,low cost and environment-friendliness.The lithium sulfur battery,which composed of sulfur cathode and mental lithium anode,is regarded to reach high energy density above 1000 Wh/kg.However,the insulating of sulfur,shuttle effect and high volume change during discharging hinder the utilization of lithium sulfur battery.It is necessary to solve the three problems at the same time.The rational design of sulfur carrier materials is therefore essential.Based on the related literatures reported in recent years,sulfur carrier materials and their electrochemical performances are reviewed.The development trend of sulfur carrier materials are prospected.
