Abstract The sluggish conversion kinetics and uneven deposition of sodium sulfide (Na 2 S) pose significant obstacles to the practical implementation room temperature sodium–sulfur (RT Na─S) batteries. To tackle these challenges, herein, a cathode host (Co‐NMCN) that enables rapid polysulfides delicate Na S nucleation is developed via integrating Co nanoparticles into N‐doping multilayer carbon network. freestanding network expedites electronic transport relives electrode expansion, while perform strong chemical adsorption with soluble polysulfide (NaPSs) Co─S bonds exhibit remarkable electrocatalytic effect on multi‐electron NaPSs. Density functional theory (DFT) calculations reveal low energy barrier for NaPSs diffusion Na₂S oxidation, which facilitates uniform across scaffold in controlled 3D process. This effectively mitigates formation irreversible by‐products prevents electrocatalyst passivation, thus enhancing overall reaction efficiency. As result, as‐prepared S@Co‐NMCN delivers an impressive reversible capacity 934.2 mA h g −1 at 0.5C maintains decay rate 0.064% per cycle over 800 cycles 0.5C.
