Gallate-MOF derived CoS 2 /C composites as an accelerated catalyst for room-temperature sodium-sulfur batteries

CoS /C microprisms with adsorption-catalysis synergistic effects were designed to be sulfur hosts in room-temperature sodium-sulfur batteries. CoS /C can act as a polysulfide mediator to inhibit the shuttle effect and as a catalyst to accelerate polysulfide redox kinetics, achieving enhanced capabil...

Zusammenfassung:CoS /C microprisms with adsorption-catalysis synergistic effects were designed to be sulfur hosts in room-temperature sodium-sulfur batteries. CoS /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 after 870 cycles at 1 A g .
