摘要
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.
