Abstract Polyethylene oxide (PEO)‐based solid polymer electrolytes (SPEs) are considered as one of the most promising candidates for next‐generation lithium metal batteries. However, their application is limited by poor electrode/electrolyte interfacial stability, low Li‐ions transference number, and weak mechanical strength. Herein, poly (urethane‐urea)‐based SPEs developed to enhance improve transport kinetics, provide superior properties. 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. As result, Li//Li solid‐state symmetric cells assembled this SPE demonstrate stable cycling over 3000 h, while LiFePO 4 retain 93.6% initial capacity after 500 cycles at rate 1C. This work presents feasible design strategy developing highly functional materials.
