Herein, a quasi-solid-state compositenelectrolyte, poly(1,3-dioxolane) (PDOL)/glassy ZIF-62 (PGZ) with fastnion transport and intimate interface contact, is fabricated via innsitu polymerization. The in situ polymerization of DOL in an electrolytenmatrix not only improves the exterior interface between electrolyte/electrodenbut also optimizes the inner interfaces among glassy particles, renderingnPGZ as an uninterrupted ionic conductor. Moreover, PGZ inherits thensuperior ionic conductivity and the robust dendrite prohibition ofnglassy MOFs originating from their grain-boundary-free nature, isotropy,nand abundant groups containing N species. As expected, our proposednPGZ exhibits a prominent ionic conductivity of 6.3 × 10–4 S cm–1 at 20 °C. Li|PGZ|LiFePO4 delivers an outstanding rate performance (103 mAh g–1 at 4C) and a stable cycling capacity (118 mAh g–1 at 1C over 1000 cycles). PGZ also presents excellent low-temperaturencycling performance with 75 mAh g–1 for 480 cyclesnat −20 °C and excellent flame retardance.
