Proton-conductive coordination polymer glass for solid-state anhydrous proton batteries

Melt-quenched coordination polymer glass shows exclusive H⁺conductivity (8.0 × 10⁻³S cm⁻¹at 120 °C, anhydrous) and optimal mechanical properties (42.8 Pa s at 120 °C), enables the operation of an all-solid-state proton battery from RT to 110 °C.
