Abstract

CoS₂/C microprisms with adsorption-catalysis synergistic effects were designed to be sulfur hosts in room-temperature sodium-sulfur batteries. CoS₂/C can act as a polysulfide mediator to inhibit the shuttle effect and as a catalyst to accelerate polysulfide redox kinetics, achieving enhanced capabilities of 623 mA h g^-1 after 870 cycles at 1 A g^-1.
