Abstract The development of rapid and stable ion‐conductive channels is pivotal for solid‐state electrolytes (SSEs) in achieving high‐performance lithium metal batteries (LMBs). Covalent organic frameworks (COFs) have emerged as promising Li‐ion conductors due to their well‐defined channel architecture, facile chemical tunability, mechanical robustness. However, the limited active sites restricted segmental motion Li + migration significantly impede ionic conductivity. Herein, a rational design strategy presented construct 3D porous COF (TP‐COF TB‐COF) using linear ditopic monomers connected via C─C C─N linkages. These COFs, integrated with polymer electrolytes, provide enhanced transport pathways stabilize anodes LMBs. TB‐COF, featuring larger pore apertures abundant ─C═N─ sites, facilitates superior conduction (8.89 × 10 −4 S cm −1 ) high transference number (0.80) by enhancing salt dissolution. LiF/Li 3 N‐rich SEI enables uniform deposition, enabling PEO‐TB‐COF SSEs achieve >1000 h stability at 1 mA cm⁻ 2 while retaining 90% capacity through 800 cycles (0.5 C) LFP||Li cells. Molecular dynamics simulations COMSOL Multiphysics modeling reveal that extended reduced interfacial diffusion barriers are key performance.

Abstract As the global energy structure transforms and renewable rapidly develops, rechargeable batteries are increasingly focus on high density, rapid charge/discharge rates, enhanced safety performance, particularly in extreme environments. Lithium metal (LMBs) have emerged as a significant research area recent years owing to capacity low electrochemical potential of lithium (Li). However, challenges, uncontrolled Li dendrite growth, unstable solid electrolyte interface separator puncture/interface incompatibility, greatly impact battery life lead failure, thus impeding commercialization. This review presents thorough analysis key challenges facing stable LMBs from multiple perspectives, alongside regulatory strategies. The methods include anode, interface, solid/liquid electrolytes, separators, pressure artificial intelligence. An in‐depth discussion operational mechanism, advantages/drawbacks is provided. Additionally, it offers succinct overview anticipated future trends challenges. A comprehensive numerous documents studies has been conducted summarize number published papers unique characteristics corresponding provides valuable recommendations for practical application other high‐energy‐density (Sodium, Potassium, Magnesium, Zinc), thereby contributing effectively implementation national strategic planning new sector.
