Abstract Carbon‐based interlayer as the secondary current collector is a typical approach for suppressing polysulfide shuttle effect in lithium‐sulfur batteries (LSBs). The effective operating lifespan determined by balance between local concentration and bearing capacity of interlayers. However, microscopic diffusion polysulfides within interlayers under multiple force fields remains unclear, particularly catalyst on multi‐scale behavior. Herein, first identification reported with coupling longitudinal osmotic transverse radioactive through revisiting Mn‐based catalysts (Mn‐X, X = N, O, or P). In addition to electric field forces during charging discharging, free sustain tension, leading radiation This adaptive adjustment optimizes distribution, mitigating risk deactivation caused excessive concentration. extent lateral positively correlated physicochemical adsorption interlayer. Specifically, stronger static demonstrates broader range. work re‐evaluates behavior interlayers, further guiding design high performance collector.
