Description
Summary:Highlights Methoxy-substituted graphdiyne (OGDY) is synthesized via an asymmetric substitution strategy, featuring a periodic alternation of electron-rich regions and electron-deficient regions, which significantly enhances the heterogeneity of charge distribution in OGDY. An enhanced regional electric potential difference design concept is proposed to address the low ionic conductivity of polymer solid-state electrolytes. The OGDY/poly(ethylene oxide) composite polymer solid-state electrolyte achieves an ionic conductivity of 1.1×10−3 S cm−1 and a high lithium-ion transference number of 0.71.
