Abstract
Lithium-sulfur batteries have received widespread attention in recent years because of their high energy density, low cost, and environmental protection. However, a series of problems are caused by polysulfides dissolution and shuttle such as loss of active substances and low utilization. Inserting a functional interlayer between the cathode and the separator is an effective way to solve these problems. We introduced the research progress of interlayer for Li-S battery in recent years. The interlayer of inhibiting polysulfide shuttles, the interlayer with low interfacial resistance and the interlayer of improving the reaction kinetics are classified and summarized. Finally, the future design directions and development prospects of the functional interlayer for Li-S battery system are given.
