Abstract Magnesium‐sulfur (Mg‐S) batteries have the advantages of high volumetric energy density, intrinsic safety, and low cost anode cathode materials. However, current obstacles that preventing practical applications Mg‐S are reflected in sluggish reaction kinetics insulative sulfur cathode, designs compatible electrolytes, surface optimization Mg against passivation. Regarding cathodes, inherent conductivity, changes, polysulfide shuttling always result depressive capacity utilization. As known, 2+ carriers coordinated with solvents electrolyte need to be desolvated before or during participating electrochemical reactions. The desolvation steps cathodic anodic redox intercoupled at electrode/electrolyte interface, which can regarded as cascade reactions different pathways. In this review, efforts deal high‐energy‐barrier processes including desolvation, migration interface interior, conversions summarized. Importantly, possible coupling manners between above highlighted. Then catalysis strategy for accelerating conversion on premise superior conductivity is further reviewed along a variety characterizations from experiments theoretical simulations. Finally, future development trends deep understanding prospected.
