Lithium-sulfur redox: challenges and opportunities

Shuangyan Lang et al.

Summary: Understanding the mechanisms and kinetics of the lithium-sulfur redox processes is crucial for increasing the utilization of active materials and improving the practical applications of Li-S batteries. Recent advances in in situ/operando characterizations have revealed the multi-step transformations of sulfur species and the visualization of sulfur distribution, polysulfide diffusion, and lithium sulfide precipitation at the interface. The development of efficient electrocatalysts to enhance reaction kinetics has also been discussed. Additional efforts are needed for scaling up production and practical applications of Li-S batteries, despite improvements in understanding the redox processes.
