Large Language Model‐Guided Design of Anti‐Swelling Hybrid Dual Network Membranes for Long‐Duration Alkaline Zinc Iron Flow Batteries

and operates stably for over 820 h without dendrite-induced failure, which surpassed the commercial Nafion212 and SPEEK benchmarks by threefold and sevenfold, respectively. This work establishes a paradigm for LLM-accelerated material discovery in addressing the stability-selectivity dilemma of ion-exchange membranes.
