Abstract Inspired by the multifunctionality and precise regulation of biological membranes, this work designs a biomimetic membrane‐like structure for lithium–sulfur (Li–S) batteries. By controlling selenization time, composition metal catalyst material's microstructure is regulated, resulting in self‐supporting 3D porous conductive network Co/CoSe 2 ‐modified carbon nanofiber (CNF) with situ grown nanotubes (CNT) (Co/CoSe @CNF‐CNT (L)). Drawing inspiration from selective permeability (L) system achieves dual‐functionality. On one hand, catalyst, possessing Lewis acid properties, provides strong binding affinity lithium polysulfides (LiPSs), effectively inhibiting their migration. Additionally, CNF CNT form microporous structure, which inhibits shuttle effect. This behavior analogous to specific proteins membranes that selectively recognize bind certain substances. other CNF‐CNT has numerous ion channels ensure efficient lithium‐ion (Li + ) transport, mirroring role or carrier membranes. Consequently, cell exhibits reversible capacity 1425.21 mAh g −1 at 1 A retains 875.33 after 500 cycles. Furthermore, cells exhibit excellent stability under high currents prolonged cycling.
