Room-temperature sodium-sulfur (RT Na-S) batteries are potential candidates for next-generation energy storage systems because of low-cost resources, high theoretical capacity, and density. However, their commercialization is hindered by the inherent shuttle effect, insulation sulfur, slow catalytic conversion. This study proposes a novel approach involving design C/CoFe alloy catalyst coupled with Ti3C2Tx MXene substrate (C/CoFe-MXene) as three-dimensional porous conductive sulfur host. Polysulfide adsorption/catalytic experiments density functional theory calculation confirmed excellent affinity strong conversion ability C/CoFe-MXene composite polysulfides. The heterostructure formed between CoFe promotes Na+ transport accelerates reaction kinetics species. Consequently, assembled RT Na-S host (2.0 mg cm-2) deliver initial specific capacity 572 mAh g-1 at 1 C. Even 5 C, battery achieves ultralong-term cycling over 5,400 cycles retention rate 61.9%, corresponding to fading 0.0089% per cycle, demonstrating outstanding high-rate tolerance. work provides new insights into preparation cathodes surface area activity using catalysts loaded on substrates in batteries.
