Abstract The presence of electrocatalysis in lithium–sulfur batteries has been proposed but not yet sufficiently verified. In this study, molybdenum phosphide (MoP) nanoparticles are shown to play a definitive electrocatalytic role for the sulfur cathode working under lean electrolyte conditions featuring low electrolyte/active material ratio: overpotentials charging and discharging reactions greatly decreased. As result, electrodes containing MoP show faster kinetics more reversible...
