The guest cation preintercalation strategy has been widely adopted to improve the performance of zinc–vanadium batteries. However, existing studies always ignore deintercalation cations. This work focuses on severe and universal phenomenon confirms unaltered capacity after deintercalation, indicating that improvement mechanism cannot be attributed role Therefore, excluding all previously researched factors for improvement, decisive factor is identified as morphology (surface area). Based electrochemically active surface area (ECSA), a quantitative relationship with intrinsic established first time. guides us enhance battery via enhancing ECSA through liquid-phase ultrasonic crushing achieve highest cation-preintercalated V2O5·nH2O (333.7 mAh g–1 at 10 A g–1). We believe enhanced plausible explanation improved hydrated vanadium oxides.

Abstract Rechargeable aqueous zinc‐sulfur batteries (AZSBs) are emerging as prominent candidates for next‐generation energy storage devices owing to their affordability, non‐toxicity, environmental friendliness, non‐flammability, and use of earth‐abundant electrodes electrolytes. However, AZSBs currently face challenges in achieving satisfied electrochemical performance due slow kinetic reactions limited stability. Therefore, further research improvement efforts crucial advancing technology. In this comprehensive review, it is delved into the primary mechanisms governing AZSBs, assess recent advancements field, analyse pivotal modifications made electrolytes enhance performance. This includes development novel host materials sulfur (S) cathodes, which capable supporting higher S loading capacities refinement electrolyte compositions improve ionic conductivity Moreover, potential applications across various platforms evaluate market viability based on scholarly contributions explored. By doing so, review provides a visionary outlook future directions driving continuous stable technology deepening understanding charge–discharge dynamics. The insights presented signify significant step toward sustainable powered by renewable sources.
