AB  - In spite of the fact that lithium metal batteries (LMBs) facilitate the 
      diversification of energy storage technologies, their electrochemical 
      reversibility and stability have long been constrained by side reactions and 
      lithium dendrite problems. While single-ion conducting polymer electrolytes 
      (SICPEs) possess unique advantages of suppressing Li dendrite growth, they deal 
      with difficulties in practical applications due to their slow ion transport in 
      general application scenarios at  approximately 25  degrees C. In this study, we develop novel 
      bifunctional lithium salts with negative sulfonylimide (-SO(2)N((-))SO(2)-) 
      anions mounted between two styrene reactive groups, which is capable of 
      constructing 3D cross-linked networks with multiscale reticulated ion 
      nanochannels, resulting in the uniform and rapid distribution of Li(+) ions in 
      the crosslinked electrolyte. To verify the feasibility of our strategy, we 
      designed PVDF-HFP-based SICPEs and the obtained electrolyte exhibits high thermal 
      stability, outstanding Li(+) transference number (0.95), pleasing ionic 
      conductivity (0.722 mS cm(-1)), and broad chemical window (greater than5.85 V) at 
      ambient temperature. As a result of the electrolyte structural merits, the 
      Li||LFP cells displayed excellent cycling stability (96.4% reversible capacities 
      after 300 cycles at 0.2C) without additional auxiliary heating. This ingenious 
      strategy is expected to providing a new perspective for advanced performance and 
      high safety LMBs.
