Metallic WO2-Promoted CoWO4/WO2 Heterojunction with Intercalation-Mediated Catalysis for Lithium–Sulfur Batteries

Caption

  • The CoWO4/WO2 heterojunction was successfully constructed through hydrothermal synthesis of precursors followed by autogenous transformation induced by hydrogen reduction.
  • The synergistic effect of CoWO4 and WO2 promotes the catalytic conversion of polysulfides and suppresses the shuttle effect.
  • The CoWO4/WO2 heterojunction demonstrates significantly enhanced catalytic performance, delivering a high capacity of 1262 mAh g−1 at 0.1 C.
