We report a hierarchical carbon host decorated with defect-rich MoO2 clusters (MoO2-x/NC) for room-temperature Na-S batteries. The defect-enhanced MoO2-x clusters, coupled with conductive carbon, not only chemically anchor polysulfides via Mo-S bonds but also catalyze their conversion. The resulting MoO2-x/NC@S cathode delivers a remarkable capacity retention of 331 mAh g-1 after 2000 cycles at 5 C, outperforming most reported Na-S cathodes. This work demonstrates the efficacy of defect-rich cluster catalysts in enabling long-lasting and high-rate sulfur electrochemistry.
