Abstract Polyethylene oxide (PEO)‐based electrolytes are essential to advance all‐solid‐state lithium batteries (ASSLBs) with high safety/energy density due their inherent flexibility and scalability. However, the inefficient Li + transport in PEO often leads poor rate performance diminished stability of ASSLBs. The regulation intermolecular H‐bonds is regarded as one most effective approaches enable efficient transport, while practical performances hindered by electrochemical instability free H‐bond donors constrained mobility highly ordered H‐bonding structures. To overcome these challenges, we develop a surface‐confined disordered system stable donor‐acceptor interactions construct loosened chain segments/ions arrangement bulk phase PEO‐based electrolytes, realizing crystallization inhibition PEO, weak coordination entrapment anions, which conducive deposition. rationally designed LiFePO 4 ‐based ASSLB demonstrates long cycle‐life over 400 cycles at 1.0 C 65 °C capacity retention 87.5 %, surpassing currently reported polymer‐based This work highlights importance confined on an battery system, paving way for future design
