Aqueous zinc ion batteries (AZIBs) featuring low cost and high safety are attracting considerable interest. More recently, ammonium vanadate, characterized by its specific capacity, is regarded as a promising cathode material for AZIBs.

To overcome these limitations, metal ions (Na+ Zn2+) pre-intercalated into vanadate to modify the interlayer spacing enhance charge transfer kinetics. Additionally, impact of different on structure properties systematically investigated. Furthermore, we successfully synthesized materials (Na0.13(NH4)0.48V2O5·0.6H2O, Na0.13-NVO) stable nanostructures optimizing pre-embedded Na+ content.

Rechargeable aqueous Zn-ion batteries are renowned for their safety, cost-effectiveness, environmental friendliness, and high capacity. However, critical issues, such as restricted electrode kinetics uncontrolled dendrite growth of Zn anodes, have hindered practical applications. Here, we propose a gradient solid-like electrolyte (GSLE) to enhance the overall performance anodes batteries. It shows room-temperature conductivity 13.3 mS cm-1 with an enhanced Zn2+ transference number 0.67. With its negatively charged network, GSLE establishes Zn2+-rich region at Zn|electrolyte interface, thereby boosting interfacial charge transfer accelerating kinetics. Moreover, in situ ZnSe-containing interphase on surface during cycling. Such effectively guides uniform deposition inhibits side reactions. As result, symmetric cells using demonstrate stabilized plating/stripping cycling over 1400 h tolerate current 15 mA cm-2. Furthermore, assembled vanadium-based full deliver remarkable capacity 125.4 mAh g-1 4 A achieve 90% retention after 1000 cycles.

Aqueous zinc-ion batteries are promising candidates for flexible energy storage devices due to their safety, economic efficiency, and environmental friendliness. However, the uncontrollable dendrite growth side reactions at zinc anode hinder commercial application. Herein, we designed synthesized a dual network self-healing hydrogel electrolyte with zwitterionic groups (PAM–PAAS-QCS), which can be used large deformations of its excellent stretchability (ε = 5100%). The incorporation into PAM–PAAS-QCS endows it high ionic conductivity (33.61 mS/cm), wide electrochemical stability window, ability suppress formation reactions. Besides, Zn//Zn symmetric cell stably plate strip 1500 h 0.5 mA/cm2, Zn//Polyaniline full retains 82.4% capacity after cycles 1 A/g. Additionally, based on both original self-healed electrolytes demonstrate good cycling stable charge–discharge performance under various bending conditions. This is expected pave way development high-performance wearable devices.
