💡 Novelty & Significance:
This work introduces a rotation-coupled guest-anion strategy using Mg(OTf)₂ in a PVDF-HFP solid electrolyte, where OTf⁻ acts as a mobile rotator synchronized with Na⁺ hopping. It lowers migration barriers, stabilizes the Na interface, and enables long-cycling solid-state sodium batteries. Screening 20 systems, it identifies anion symmetry and rotational barriers as design criteria.
