“…To induce uniform Liion flux, Yue et al in situ engineered a highly nitrogen-rich COF on Li-metal surface to form multiple-site lithiophilic protection interface (COF@Li, Figure 4e). [52] The results confirmed the critical role of COF in preventing interface reconstruction and fracture as well as dendrite growth during the plating/stripping processes, and further demonstrated this by maintaining Coulombic efficiency and improving ion mobility (Figure 4f-h).…”

Alkali metals (Li, Na, and K) and multivalent metals (Zn, Mg, Ca, and Al) have become star anodes for developing high‐energy‐density rechargeable batteries due to their high theoretical capacity and excellent conductivity. However, the inevitable dendrites and unstable interfaces of metal anodes pose challenges to the safety and stability of batteries. To address these issues, covalent organic frameworks (COFs), as emerging materials, have been widely investigated due to their regular porous structure, flexible molecular design, and high specific surface area. In this minireview, we summarize the research progress of COFs in stabilizing metal anodes. First, we present the research origins of metal anodes and delve into their advantages and challenges as anodes based on the physical/chemical properties of alkali and multivalent metals. Then, special attention has been paid to the application of COFs in the host design of metal anodes, artificial solid electrolyte interfaces, electrolyte additives, solid‐state electrolytes, and separator modifications. Finally, a new perspective is provided for the research of metal anodes from the molecular design, pore modulation, and synthesis of COFs.

“…To further explain the ZMOF-NSC protective layer’s impact on ion transport mechanisms, the activation energy (E a ) was determined by fitting temperature-varying Nyquist data (Figure S8a,b) to the Arrhenius model (Figure c) . The activation energy for Na + diffusion through the SEI of ZMOF-NSC is 74.16 kJ mol –1 , compared to 78.30 kJ mol –1 for bare Na, which proves that Na + can pass through the modified artificial layer more easily and diminishes the polarization within the battery throughout the cycling process. , Additionally, as shown in Figure d and Figure S9, the Na + transference number ( t Na + ) for ZMOF-NSC is 0.93, surpassing that of the bare Na metal anode (0.80). The variation in t Na + can be attributed to the difference in the penetration ability within the interface layer.…”

Sodium−metal batteries, heralded for high energy density and cost-effectiveness, are compromised by an unstable solid electrolyte interphase (SEI) and dendrite formation, which hinder practical applications. Herein, a zirconium-based metal−organic framework nanostructure coating (ZMOF-NSC) was constructed in a low-loss, flexible manner. Comprehensive studies show that ZMOF-NSC, with its periodically ordered nanochannels and organized pore structures, enhances ion transport and decreases the Na + migration energy barrier, thus ensuring uniform ion flux and achieving uniform spherical deposition. Additionally, ZMOF-NSC facilitates partial desolvation, catalyzing the formation of an inorganic-rich, dual-layered SEI that effectively protects the anode and suppresses dendrite formation. Consequently, the ZMOF-NSC@Na symmetric battery exhibits an impressive lifespan of over 2500 h, demonstrating extended operational longevity. The Na 3 V 2 (PO 4 ) 3 ∥ZMOF-NSC@Na batteries demonstrate exceptional cycling stability with 81% capacity retention after 2000 cycles at 10 C, maintaining stability over 3000 cycles at 20 C. Moreover, the NVP∥ZMOF-NSC@Na battery achieves an energy density of 370 Wh kg −1 and a power density of 10,484 W kg −1 , indicating superior durability and performance. This significant finding highlights the significant potential of structured MOFs to induce a dual-layered SEI, advancing the commercialization of durable, dendrite-free sodium metal batteries. The precise design of self-assembled pore structures and surface active sites in MOFs demonstrates significant potential in advancing the commercialization of durable, dendrite-free electrodes of metal-based rechargeable batteries.
