Abstract

Commercial lithium-ion batteries (LIBs) are incapable of satisfying the increasing demand for emerging electronic devices due to their limited energy density. Among the next-generation batteries, lithium-sulfur (Li-S) batteries are becoming a promising energy-storage system due to their high theoretical energy density and natural abundance of sulfur. However, the shuttle of soluble polysulfide intermediates between two electrodes, as well as the problem on Li metal anode，lower the utilization of active material and lead to the loss of specific capacity and rapid capacity fading. All the above challenges limit the further application of Li-S batteries. Recently, various novel battery configurations have been reported in Li-S system, such as the construction design of multi-functional separator, cathode interlayer, brand sulfur hosts, as well as hybrid anode. The novel structure designs have been proved effective to relieve the intrinsic problems of Li-S batteries. Herein, we summarize the developments in separator modification and carbon-based interlayer in Li-S batteries. In the end, a perspective for future research direction of Li-S batteries is also presented.
