The (urethane‐urea) structure integrates abundant polar groups rigid conjugated moieties, which facilitate interactions with anions salt in SPEs, promoting number supporting formation a LiF‐rich electrolyte interphase (SEI) guide uniform deposition suppress dendrite growth. Furthermore, supramolecular crosslinked network formed through multiple hydrogen bonds π‐π stacking interactions, enhancing strength toughness SPEs.

Abstract Polyethylene oxide (PEO)‐based all‐solid‐state lithium metal batteries (ASSLMBs) are strongly hindered by the fast dendrite growth at Li metal/electrolyte interface, especially under large rates.

Abstract Progress in commercializing solid polymer electrolytes (SPEs) for lithium metal batteries (LMBs) has been impeded by challenges, like concentration polarization, non‐uniform Li + flux, and an unstable electrolyte interface (SEI), which contribute to dendrite formation.
