V O decorated carbon nanofibers (CNFs) are prepared and used as a multifunctional interlayer for a lithium-sulfur (Li-S) battery. V O 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.
VO 修饰的碳纳米纤维（CNFs）被制备并用作锂硫（Li-S）电池的多功能中间层。VO 锚定在 CNFs 上不仅可以通过强吸附和氧化还原反应抑制多硫化物的穿梭效应，还可以作为高电位势垒抑制电池中的自放电行为。结果，具有高容量和长循环寿命的 Li-S 电池可以长时间储存和休息，而不会出现明显的容量衰减。
