Summary: Developing ideal electrocatalysts is crucial for accelerating sulfur redox kinetics in both discharging and charging processes of high-performance lithium-sulfur batteries. In this study, defect-rich cation-doped V2O5 yolk-shell microspheres are used as a catalytic host for sulfur. The doping of W or Mo cations leads to broadened lattice spacing of V2O5 and enriched oxygen vacancy defects, providing sufficient active sites for chemically anchoring polysulfides and facilitating mutual conversion between different sulfur intermediates. The S/W-V2O5 cathode demonstrates excellent discharging capacity and cycle stability, even under high sulfur loading and minimal electrolyte/sulfur ratio conditions. This work offers a new strategy to enhance sulfur redox kinetics in Li-S batteries.
