Our research group has recently published a comprehensive review article addressing the prominent challenges associated with vanadium-based materials in aqueous zinc-ion batteries. Vanadium-based materials featuring tunnel or layered structures have garnered substantial attention due to their promising high theoretical capacity and diverse structural characteristics. Nevertheless, their widespread adoption has been hindered by issues such as material dissolution, by-product formation, and sluggish kinetics when used in aqueous electrolytes, resulting in less than satisfactory long-term cycling stability. These obstacles significantly restrict the practical utility of vanadium-based cathodes in aqueous zinc-ion batteries.
In this review, we focus on elucidating the primary issues encountered by vanadium-based cathodes in practical aqueous zinc-ion batteries and offer potential solutions to mitigate these challenges. The article places a strong emphasis on introducing vanadium-based cathodes, elucidating ion storage mechanisms, highlighting key parameters influencing their performance, and presenting recent progress in addressing the aforementioned hurdles.
To conclude, we also outline the prospective development trajectory for practical water-based zinc-ion batteries, highlighting the need for continued research and innovation to overcome the existing limitations and promote the widespread adoption of this promising energy storage technology.
