摘要：
It is evident that the polysulfide will take place the shuttle effect between the cathode and anode in the Li-S battery. This is proved by many experiment studies in the past decades. Therefore, the most efficient method for improving the electrochemical performance of Li-S battery is inhibiting this shuttle effect. Based on this idea, we design a free-standing carpet-like TiO2 nanofiber skeleton interlayer in the Li-S battery. This advanced interlayer could stem the transfer of soluble polysulfide, which shuttle between cathode and anode. Besides, the nanofiber structure in the carpet-like TiO2 nanofiber skeleton interlayer provides channels for the rapid transport of lithium-ions. Considering all these advantages, the as-prepared TiO2 interlayer shows perfect electrochemical performance for the Li-S batteries.
