A Bifunctional Fibrous Scaffold Implanted with Amorphous Co₂P as both Cathodic and Anodic Stabilizer for High-Performance Li─S Batteries.

ABSTRACT: The shuttling of lithium polysulfides (LiPSs) and the formation of lithium dendrites have substantially impeded the practical application of lithium-sulfur (Li─S) batteries. To simultaneously solve these issues, a porous carbon fibrous scaffold embedded with amorphous Co₂P (A─Co₂P) is designed as both a cathodic and anodic stabilizer to construct high-rate and long-life Li─S batteries. The meticulously designed self-supporting membrane with an integrated carbon network and porous structure offers superior conductivity and copious spaces for uniform Li₂S precipitation in the cathode and Li deposition in the anode. Moreover, the incorporated A─Co₂P provides abundant unsaturated sites, which can not only facilitate the exposure of active sites but a
