NOVEL ALL-SOLID-STATE ELECTROLYTES BASED ON ORGANOBORON COVALENT ORGANIC NETWORKS

An organoboron covalent organic network impregnated with at least one salt selected from alkali metal salts and alkaline-earth metal salts. The impregnated organoboron covalent organic network is substantially free of organic solvent. A method for preparing an impregnated organoboron covalent organic network, the use thereof as a solid electrolyte in an all-solid-state battery, and a separator for an all-solid-state battery, an electrode for an all-solid-state battery and an all-solid-state battery comprising such an impregnated organoboron covalent organic network.
