LiFSI and LiTFSI are combined to form a binary-salt electrolyte with higher ionic conductivity and lower viscosity for a Li-S battery. A high capacity and stable cycle performance of the sulfur-based composite with high sulfur content are realized in the electrolyte, accompanied simultaneously by the homogeneous lithium deposition on the anode.
双氟磺酰亚胺锂（LiFSI）和双三氟甲烷磺酰亚胺锂（LiTFSI）组合形成一种二元盐电解质，用于锂硫电池，具有更高的离子电导率和更低的粘度。在该电解质中实现了高硫含量硫基复合材料的高容量和稳定循环性能，同时阳极上锂的沉积也较为均匀。
