Abstrakt: CoS 2 /C microprisms with adsorption-catalysis synergistic effects were designed to be sulfur hosts in room-temperature sodium-sulfur batteries. CoS 2 /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 .
