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

Zinc-ion batteries are promising for large-scale electrochemical energy storage systems, which still suffer from interfacial issues, e.g., hydrogen evolution side reaction (HER), self-corrosion, and uncontrollable dendritic Zn electrodeposition. Although the regulation of electric double layer (EDL) has been verified principle to select additive as regulator is misted. Here, several typical amino acids with different characteristics were examined reveal behaviors in regulated EDL on anode.

Abstract Dendrite growth and other side‐reaction problems of zinc anodes in aqueous zinc‐ion batteries heavily affect their cycling lifespan Coulombic efficiency, which can be effectively alleviated by the application polymer‐based functional protection layer on anode. However, utilization rate groups is difficult to improve without destroying polymer chain. Here, a simple well‐established strategy proposed controlling orientation (─SO 3 H) assist optimization anodes. Depending electrostatic effect, surface‐enriched ─SO H increase ionic conductivity homogenize Zn 2+ flux while inhibiting anionic permeation. This approach avoids destruction backbone over‐sulfonation amplifies effect groups. Therefore, modified sulfonated polyether ether ketone (H‐SPEEK) coating‐optimized anode capable longtime stable plating/stripping, moreover an enhanced steadiness under high current densities also detected series with different cathode materials, achieved inclusion H‐SPEEK coating causing any harmful effects electrolyte cathode. work provides easy efficient further optimize plating/stripping cations metal electrodes, sheds lights scale‐up high‐performance battery technology.
