Abstract Although polymer electrolytes have shown great potential in solid‐state lithium metal batteries (LMBs), the chain segments anchor movement of ions (Li + ), which induces low ionic conductivity and limits their application. Herein, a strategy harnessing ion‐dipole interactions is proposed to liberate from chains. The adiponitrile (ADN) molecular dipole with strong bond moment (C≡N, 11.8 × 10 −30 C m) introduced into polyvinylidene fluoride‐co‐hexafluoropropylene (PVDF‐HFP) matrix, achieving an electrolyte high 5.1 −4 S cm −1 at 30 °C. It demonstrated that interaction between C≡N Li weakens F···…Li , facilitating dissociation liberating Moreover, hybrid unsaturated solvation structure formed ADN dipole, PVDF‐HFP chain, TFSI − anion, corresponding solvent‐separated ion pair (SSIP) structure. Thus, obtained realizes lithium‐ion transference number (0.74). Consequently, assembled symmetric cell delivers stable stripping/plating reversibility over 900 h.
