Abstract：

The　development　of　the　commercial　lithium-sulfur　(Li-S)　batteries　have　been　severely　limited　due　to　the　disgusting　shuttle　effect　and　sluggish　redox　kinetics　of　lithium　polysulfides　(LiPSs)　intermediates.　Herein,　cobalt　phosphide　(CoP)　nanoparticles　embedded　into　carbon　spheres　(CoP@C)　as　an　interlayer　on　commercial　polypropylene　(PP)　separator　are　designed　through　a　facile　co-precipitation　method　to　address　the　above　issues.　The　spherical　CoP@C　composite　with　numerous　active　sites　can　not　only　capture　the　LiPSs　via　strong　chemical　anchoring　ability　effectively,　but　also　have　good　electrocatalytic　ability　to　decrease　the　redox　conversion　barrier　and　enhance　Li+　ion　transport,　ultimately　promote　the　LiPSs　conversion　kinetics.　Therefore,　the　Li-S　batteries　with　CoP@C-PP　separator　show　excellent　electrochemical　performance　with　high　initial　capacity　of　1213　mAh　g　−1　at　0.2　C,　excellent　cyclability　with　a　low　capacity　fading　rate　of　0.058%　per　cycling　upon　long-term　800　cycles　at　1.0　C,　and　a　superior　rate　performance　with　654　mAh　g　−1　even　at　5.0　C.　©　2022
