锂硫电池电解质研究进展
发布时间：2019-01-03 15:39
【摘要】：锂硫电池由于其高能量密度(理论高达2600 Wh/kg)、低成本、环境友好等优点而广受关注.但是锂硫电池仍存在正极活性物质利用率低、循环性能差等问题.造成这些问题的主要原因是易溶于有机电解液的中间产物聚硫锂Li2Sn(4≤n≤8)和不溶于有机电解液的硫化锂造成的.简要介绍了锂硫电池体系的主要问题,并结合本研究小组的研究,对锂硫电池用电解质体系从有机电解液组成、电解液添加剂、聚合物电解质和无机固体电解质等方面进行了详细的综述,最后对电解质的发展前景进行了展望.
[Abstract]:Lithium-sulfur batteries have attracted much attention due to their high energy density (theoretical value up to 2600 Wh/kg), low cost and environmental friendliness. However, lithium-sulfur batteries still have some problems, such as low utilization of positive active substances and poor cycling performance. These problems are mainly caused by polysulfide lithium Li2Sn (4 鈮，
