Abstract Solid polymer electrolytes (SPEs) have garnered considerable interest in the field of lithium metal batteries (LMBs) owing to their exceptional mechanical strength, excellent designability, and heightened safety characteristics. However, inherently low ion transport efficiency poses a major challenge for application LMBs. To address this issue, covalent organic framework (COF) with ordered channels, chemical stability, large specific surface area, designable multifunctional sites has shown promising potential enhance lithium-ion conduction. Here, we prepared an anionic COF, TpPa-COOLi, which can catalyze ring-opening copolymerization cyclic lactone monomers situ fabrication SPEs. The design leverages high area COF facilitate absorption polymerization precursor within pores, forming additional COF-polymer junctions that pathways. partial exfoliation achieved through these improved its dispersion matrix, preserving channels facilitating across grain boundaries. By controlling variables alter crystallinity TpPa-COOLi presence –COOLi substituents, long-range order substituents exhibited superior electrochemical performance. This research demonstrates constructing high-performance SPEs
