Abstract Solid‐state lithium batteries have attracted significant interest due to their potential enhance the safety and energy density of modern storage systems. However, challenges such as low ionic conductivity poor interfacial compatibility hindered widespread adoption. In this study, a novel hydrogen‐bonded organic framework (HOF) composite polymer electrolyte (HCPG@SPE) is developed by integrating trimesic acid melamine‐based HOFs with natural matrix composed gelatin chitosan. The hydrogen‐bonding interactions between HOF in HCPG@SPE impart remarkable mechanical strength thermal stability. Additionally, weak lithium‐ions, its anion adsorption capacity, effectively generates more free facilitating migration while inhibiting movement. Electrochemical tests revealed that exhibited high (5.74 × 10⁻ 3 S cm⁻¹ at 30 °C), favorable lithium‐ion transference number (0.71), an extended electrochemical stability window (5.4 V). metal utilizing achieved outstanding performance, LFP| HCPG@SPE| Li cells retaining 98% capacity after 1000 cycles 5 C, NCM811| demonstrating stable cycling for 700 1 C. results suggest HOF‐based holds promise next‐generation high‐performance solid‐state batteries.

Abstract Alkali metal chalcogen batteries (such as lithium–sulfur/selenium, sodium–sulfur systems, abbreviated Li‐S/Se and Na‐S) have become an important direction for the next generation of high‐energy due to their ultra‐high theoretical energy density cost advantages, but problem rapid capacity decay needs be solved urgently. Covalent organic frameworks (COFs) provide a new idea improving battery performance high specific surface area tunable structure: porous structure can sufficient electrochemical reaction sites optimize ion transport paths, thereby charge‐discharge efficiency rate performance. In this paper, research progress COFs in alkali is systematically reviewed.

Covalent organic frameworks (COFs) aerogels solve the restrictions on processability and application caused by insolubility non-fusibility of powders while avoiding inaccessibility pore structures dense stacking. At current start-up stage where COFs are scarce difficult to synthesize, design generalized synthetic methods play an indispensable role in guiding developing aerogels. Moreover, evolving functionality COF is equal vital, which achieves higher performance broader practical applications. In this work, for first time, processable BrCOFs have been synthesized without vacuum seven kind polar solvents, realizes general preparation It extremely friendly inapplicability some scenarios. Furthermore, Suzuki-Miyaura cross-coupling reaction, endows with cyano groups (-CN), trifluoromethyl (-CF
