Highly conductive, crystalline, polymer electrolytes, β‐cyclodextrin (β‐CD)–polyethylene oxide (PEO)/LiAsF 6 and β‐CD–PEO/NaAsF 6 , were prepared through supramolecular self‐assembly of PEO, β‐CD, and LiAsF 6 /NaAsF 6 . The assembled β‐CDs form nanochannels in which the PEO/X + (X=Li, Na) complexes are confined. The nanochannels provide a pathway for directional motion of the alkali metal ions and, at the same time, separate the cations and the anions by size exclusion.
