Abstract Aqueous zinc‐ion batteries (AZIBs) have garnered significant interest for their potential in large‐scale energy storage, attributed to high safety and low cost. Nonetheless, issues such as limited cycling lifespan coulombic efficiency (CE) associated with dendrite formation uncontrollable side reactions on the Zn metal anode pose challenges that restrict practical applications. Herein, a dielectric filler‐assisted artificial hybrid interphase is constructed surface address faced by aqueous electrolytes. TiO 2 nanoparticles special properties promote solvation process carboxymethyl cellulose (CMC) acts physical barrier suppressing adverse blocking dendrite. Consequently, symmetric cell using modified zinc achieves prolonged cycle life of over 2500 h at 1 mAh cm −2 . Furthermore, full vanadium‐based cathode delivers excellent electrochemical performance (over 600 cycles A g −1 ). This research offers an efficient scalable approach enhance anodes.

Aqueous zinc–iodine batteries (ZIBs) based on the reversible conversion between various iodine species have garnered global attention due to their advantages of fast redox kinetics, good reversibility, and multielectron feasibility. Although significant progress has been achieved in ZIBs with two-electron I–/I2 pathway (2eZIBs), relatively low energy density hindered practical application. Recently, four-electron I–/I2/I+ electrochemistry (4eZIBs) shown a improvement density. Nonetheless, use 4eZIBs is challenged by poor reversibility polyiodide shuttling during I+ hydrolysis I2/I+ conversion. In this Review, we thoroughly summarize fundamental understanding two ZIBs, including reaction mechanisms, limitations, strategies. Importantly, provide an intuitive evaluation assess potential highlight critical impacts Zn utilization rate. Finally, emphasize cost issues associated electrodes propose closed-loop recycling routes for sustainable storage ZIBs. These findings aim motivate application advanced promote storage.

Aqueous zinc-ion batteries have gained significant attention due to their high safety and low cost. However, the cation concentration gradient at anode/electrolyte interface often causes serious Zn dendrites side reactions. Herein, cross-linked ion channels were constructed on anode surface by antipolyelectrolyte effect of zwitterionic polymer carboxymethyl chitosan (CMCHS) molecules, which is induced transient difference initial Zn2+ deposition process. The CMCHS endow with homogeneous ions electron distributions. Simultaneously, molecules enter into solvation structures H2O are removed, limiting activity solvated molecules. Therefore, dendrite growth water significantly suppressed, resulting in excellent electrochemical performance anodes. An average Coulombic efficiency 99.58% achieved, much superior case conventional ZnSO4 electrolyte. To illustrate feasibility CMCHS-contained electrolyte, Zn||V2O5 full assembled exhibited enhanced performance.

Abstract Aqueous zinc‐ion batteries (AZBs) degrade under a high current density due to the existence of interfacial turbulence with severe concentration polarization. Herein, an ion redistribution gel electrolyte is introduced stabilize electrode‐electrolyte interface by regulating gradient. Negatively charged carboxymethyl groups in starch ether polymer (PCMS) electrolytes can preferentially regulate at anode interface. The quasi‐solid PCMS dissipate charge accumulation caused differences, which beneficial for achieving excellent electrochemical stability densities. As result, symmetric Zn cells be cycled more than 2000 h 40 mA cm −2 . Furthermore, Zn//I 2 cell using also sustained cycling over 8000 cycles, and pouch exhibited practical deformable applications flexible devices. This work highlights effective approach enhancing stability, potentially advancing development highly reversible AZBs.
