Lithium-sulfur (Li-S) batteries have attracted intensive attention owing to their ultrahigh theoretical energy density. Nevertheless, the practical application of Li-S batteries is prevented by uncontrollable shuttle effect and retarded reaction kinetics. To address the above issues, lithium fluoride (LiF) was employed to regulate the surface chemistry of routine separator. The functional separator demonstrates a great ability to suppress active S loss and protect lithium anode. This work provides a facile strategy for the development of advanced Li-S batteries.

用 LiF 调节先进锂硫电池隔膜的表面化学

锂硫（Li-S）电池因其超高的理论能量密度而备受关注。然而，无法控制的穿梭效应和延迟的反应动力学阻碍了锂硫电池的实际应用。为了解决上述问题，采用氟化锂 (LiF) 来调节常规隔膜的表面化学。功能性隔膜表现出抑制活性硫损失和保护锂负极的强大能力。这项工作为开发先进的锂硫电池提供了一种简便的策略。
