High-Density Oxygen Doping of Conductive Metal Sulfides for Better Polysulfide Trapping and Li₂ S-S₈ Redox Kinetics in High Areal Capacity Lithium-Sulfur Batteries.

ABSTRACT: Exploring new materials and methods to achieve high utilization of sulfur with lean electrolyte is still a common concern in lithium-sulfur batteries. Here, high-density oxygen doping chemistry is introduced for making highly conducting, chemically stable sulfides with a much higher affinity to lithium polysulfides. It is found that doping large amounts of oxygen into NiCo₂ S₄ is feasible and can make it outperform the pristine oxides and natively oxidized sulfides. Taking the advantages of high conductivity, chemical stability, the introduced large Li-O interactions, and activated Co (Ni) facets for catalyzing S_n ^2- , the NiCo₂ (O-S)₄ is able to accelerate the Li₂ S-S₈ redox kinetics. Specifically, lit
