Lithium-sulfur batteries (LSBs) are widely acknowledged as the most promising energy storage systems for the future, primarily due to their remarkably high theoretical energy density. Nonetheless, the advancement of LSBs encounters various hurdles, including the substantial expansion of the cathode material, inadequate conductivity of the active material S and discharge product Li2S, the evident shuttle effect of lithium polysulfide (LiPS), and the sluggish sulfur conversion kinetics. These challenges become particularly evident when handling high sulfur loading. The issue of uneven Li dendrite growth at the anode significantly affects the long-term functionality and safety of batteries. Consequently, there is a pressing requirement for battery designs that effectively tackle these challenges. Metal phosphide, owing to its remarkable catalytic activity and distinctive physicochemical properties, has been extensively investigated and is anticipated to serve as a bifunctional material in
