Abstract
Abstract The poor structural stability of polymer electrolytes and sluggish ion transport kinetics of interfaces with cathode limit the fundamental performance improvements of polymer all‐solid‐state lithium metal batteries under high voltages. Herein, it is revealed that by introducing dielectric BaTiO 3 in an in‐situ polymerized composite solid‐state electrolyte, the generated interaction between the ether group of polymer electrolyte and dielectric material could effectively regulate the lithium‐ion (Li + ) coordination structure to achieve an oxidative potential higher than 5.2 V. The dielectric BaTiO 3 with spontaneous polarization also weakens the space charge layer effect between the cathode and…
