V2O5 decorated carbon nanofibers (CNFs) are prepared and used as a multifunctional interlayer for a lithium–sulfur (Li–S) battery. V2O5 anchored on CNFs can not only suppress the shuttle effect of polysulfide by the strong adsorption and redox reaction, but also work as a high-potential dam to restrain the self-discharge behavior in the battery. As a result, Li–S batteries with a high capacity and long cycling life can be stored and rested for a long time without obvious capacity fading.
