“…Concurrently, ball‐milled HOFs‐8 offers adequate exposure of the active sites for sodium ions storage, increasing the reaction kinetics, and consequently, the electrochemical performance is improved. [ 44 ] Moreover, the elastic hydrogen‐bonded structure in HOFs‐8 successfully restricted the structural deterioration during cycling, which preserved HOFs morphology, thereby improving the lasting cycling performance of the HOFs‐8 electrodes. The SEM and TEM images in Figure S10 (Supporting Information) show that the HOFs‐8 maintained its lamellar architecture within 200 cycles.…”

Hydrogen‐bonded organic frameworks (HOFs) are considered as potential choice for future energy storage systems due to their adjustable chemistry, environment friendliness, and cost‐effectiveness. In this study, structurally stabilized and aldehyde‐tuned hydrogen‐bonded organic frameworks (HOFs‐8) are designed and prepared to contain arrayed electronegative sites for sodium‐ion storage. Benefitting from the flexible hydrogen bond and unique structural symmetry, HOFs‐8 can achieve efficient utilization of the active sites and fast transport of sodium ions and electrons. The HOFs‐8 electrode exhibits an impressive lifespan of 5000 cycles at 3.66 A g−1 (20 C). In situ Fourier Transform infrared spectroscopy (in situ FT‐IR) and ex situ X‐ray Photoelectron Spectroscopy (ex situ XPS) analyses are performed to illustrate the mechanism of sodium‐ion storage involving aldehyde‐tuned C═O. Additionally, flexible hydrogen bonds in HOFs materials with unique structural symmetries are investigated to elucidate the mechanism of hydrogen bonding for improving their electrochemical properties. Density functional theory (DFT) simulations verified that HOFs‐8 has excellent Na+ diffusion kinetics, enabling it to demonstrate outstanding rate capability. This work offers insight into the design of new electrodes and improved HOFs, which are expected to have tremendous potential in energy storage systems.

Covalent organic frameworks (COFs) are porous structures emerging as promising electrode materials due to their high structural diversity, controlled and wide pore network, and amenability to chemical modifications. COFs are solely composed of periodically arranged organic molecules, resulting in lightweight materials. Their inherent properties, such as extended surface area and diverse framework topologies, along with their high proclivity to chemical modification, have positioned COFs as sophisticated materials in the realm of electrochemical energy storage (EES). The modular structure of COFs facilitates the integration of key functions such as redox‐active moieties, fast charge diffusion channels, composite formation with conductive counterparts, and highly porous network for accommodating charged energy carriers, which can significantly enhance their electrochemical performance. However, ascribing intricate porosity and redox‐active functionalities to a single COF structure, while maintaining long‐term electrochemical stability, is challenging. Efforts to overcome these hurdles embrace strategies such as the implementation of reversible linkages for structural flexibility, stimuli‐responsive functionalities, and incorporating chemical groups to promote the formation of COF heterostructures. This review focuses on the recent progress of COFs in EES devices, such as batteries and supercapacitors, through a meticulous exploration of the latest strategies aimed at optimizing COFs as advanced electrodes in future EES technologies.

“…A recent study involved modifying the COF structure by finely adjusting its interlayer distance using ball mill exfoliation to create COF nanosheets (1,3,5-triformyl phloroglucinol and Hydrazine-based COF). [66] These nanosheets were then deposited onto a polyethylene membrane through a vacuum-assisted self-assembly process, resulting in preparing an electrolyte membrane with approximately 9 μm thickness. Remarkably, when applied in a Li-LiFePO 4 battery, these COF-nanosheet/PE membrane exhibited exceptional cycling stability, enduring an initial discharge capacitance of 152 mA h g À 1 at 0.5 C. Similarly, within a LiÀ S battery system, the same membrane setup demonstrated a capacitance retention of 580 mA h/g after 100 cycles at 0.2 C. The electrochemical performance of COF-nanosheet/PE membrane in Li-LiFePO 4 and LiÀ S batteries are represented in Figure 2c and d.…”

Lithium batteries have been widely utilized in wide‐ranging electronic devices, from smartphones to electric vehicles. This review explores a new area of advanced materials for energy storage application, especially focusing on solid electrolyte membranes for lithium battery. To enhance the overall performance of lithium batteries, researchers are studying solid electrolyte membranes, aiming to overcome the limitations of liquid electrolytes and other traditional membranes. Recently, metal‐organic frameworks (MOFs) and covalent‐organic frameworks (COFs) exhibit promising characteristics due to their highly organized porous nature and structural properties. These frameworks hold significant potential as a viable component for lithium battery systems, especially in advanced separator/electrolyte setups. Because of their adjustable structural design, MOFs and COFs have the capacity to enhance battery performance by facilitating ion movement, providing superior mechanical stability, and safety. This review provides insight into the recent progress achieved by integrating MOFs and COFs into solid electrolyte membranes for lithium batteries, highlighting their potential advantages, associated challenges, and future research avenues.
