ABSTRACT Aqueous zinc‐ion batteries (AZIBs) are promising for large‐scale energy storage due to zinc's abundance, safety, and low cost. Vanadium‐based cathodes offer high energy density through multi‐electron redox reactions and structural versatility. However, their performance is limited by material dissolution, by‐product accumulation, and structural degradation during cycling. Electrolytes, as the medium governing ion transport and interfacial processes, critically determine the interfacial environment and reaction kinetics. Advanced electrolyte engineering thus offers a viable route to address these failure mechanisms. This review systematically outlines the dissolution pathways and failure modes of vanadium‐based electrodes, followed by an analysis of electrolyte customization strategies, including solute coordination tuning, solvent molecule regulation, and novel electrolyte designs. These approaches aim to suppress parasitic reactions and maintain electrode integrity. Future perspectives highlight integrating AI, high‐throughput simulation, and sustainable chemistry to guide the development of durable, high‐performance vanadium‐based AZIBs.
