Abstract Covalent organic framework (COF) materials, known for their robust porous character, sustainability, and abundance, have great potential as cathodes aqueous Zn‐ion batteries (ZIBs). However, application is hindered by low reversible capacity discharge voltage. Herein, a donor–acceptor configuration COF (NT‐COF) utilized the cathode ZIBs. The cell exhibits high voltage plateau of ≈1.4 V 214 mAh g −1 at 0.2 A when utilizing Mn 2+ electrolyte additive in ZnSO 4 electrolyte. synergistic combination mechanism proposed, involving deposition/dissolution reactions Zn SO (OH) 6 ·4H 2 O co‐(de)insertion H + 2− NT‐COF. Meanwhile, NT‐COF with facilitates efficient generation separation electron‐hole pairs upon light exposure, thereby enhancing electrochemical within battery. This leads to reduction charging internal overvoltage, ultimately minimizing electricity consumption. Under ambient weather conditions, an average 430 on sunny days maintains consistent cycling stability duration 200 cycles (≈19 days) . research inspires advancement Zn‐organic high‐energy‐density energy storage systems or photo‐electrochemical batteries.

Abstract Zinc (Zn) emerges as an ideal anode for aqueous‐based energy storage devices because of its safety, non‐toxicity, and cost‐effectiveness. However, the reversibility zinc anodes is constrained by unchecked dendrite proliferation parasitic side reactions. To minimize these adverse effects, a highly oriented, crystalline 2D porous fluorinated covalent organic framework (denoted TpBD‐2F) thin film in situ synthesized on Zn protective layer. The zincophilic hydrophobic TpBD‐2F provides numerous 1D nanochannels, which facilitate hopping/transfer 2+ repel H 2 O infiltration, thus regulating flux inhibiting interfacial corrosion. resulting enabled stable plating/stripping symmetric cells over 1200 h at mA cm −2 . Furthermore, assembled full (Zn‐ion capacitors) deliver ultra‐long cycling life 100 000 cycles current density 5 A g −1 , outperforming nearly all reported materials.

Abstract Aqueous zinc‐ion batteries (AZIBs), candidates for large‐scale energy storage, face limitations due to the poor reversibility of zinc anodes. It reports on pyridine derivatives with high donor characteristics, including 2‐chloro‐1‐methylpyridinium iodide (CMPI) and pyridine‐2‐acetaldoxime methyl (PAMI), as effective additives. At lower concentrations, these additives markedly curtail dendrites formation evolution hydrogen anode, thereby prolonging AZIBs life. Through a combination theory experiments, impact side‐chain groups kinetic process depositioni is elucidated. In contrast PAM + , CMPI demonstrates enhanced adsorption self‐assembles at anode‐electrolyte interface, forming barrier free water protective ZnI layer via I − ion integration. This dual‐layer strategy boosts plating/stripping by 100‐fold achieves coulombic efficiency 99.7% in zinc–copper half‐ batteries. The findings advance understanding electrolyte additive structures deposition, providing molecular framework screening aqueous metal‐ion

Abstract Aqueous ammonium‐ion (NH 4 + ) batteries (AAIBs) have recently been considered as attractive alternatives for next‐generation large‐scale energy storage systems, on account of their cost‐effectiveness, nonflammability, less corrosive, small hydrated ionic radius, and rapid NH diffusion kinetics. In addition, the tetrahedral structure exhibits preferential orientation characteristics, resulting in a different electrochemical mechanism from spherical charge carriers such Li , Na K . Therefore, unlocking ‐ion mechanisms host electrode materials is pivotal to advancing design high‐performance AAIBs. Organic materials, with customizable, flexible, stable molecular structures, along ease recycling disposal, offer tremendous potential. However, development cutting‐edge organic specifically AAIBs remains an exciting, yet largely untapped, frontier.
