The lean electrolyte in lithium‐sulfur (Li‐S) batteries commonly presents inhomogeneous distribution and inadequate electrolyte wetting, resulting in uneven electrochemical reaction interface, suboptimal performance, and cell failure or accelerated degradation. Non‐destructive operando /in situ methods…
Lithium–sulfur batteries (LSBs) are considered as one of the most promising next‐generation energy‐storage devices because of their high energy density. However, the long‐term use of LSBs is mainly limited by polysulfide shuttling and cathode structural degradation caused by volume changes during charging…
