Solid organic ion conductors have garnered attention as a promising alternative to the widely investigated inorganic ion conductors in all-solid-state Li batteries (ASSLBs). However, their sluggish Li+ conduction has hindered their practical application. Here, we present polymer-implanted, Li-sulfonated covalent organic frameworks (Li-COFs@P) as a class of solvent-free solid organic single-ion conductor based on ion–dipole interaction. The Li-COFs@P promotes the dissociation and migration of Li+ in one-dimensional directional ionic channels by weakening ion (Li+ dissociated from the COFs)–dipole (oxygen from the implanting poly(ethylene glycol) diacrylate) interaction. Additionally, a single-ion transport behavior is achieved, outperforming those of previously reported solid organic single-ion conductors based on traditional ion–ion interaction. Consequently, the Li-COF@P enables reversible Li plating/stripping on Li-metal anodes and..
