Research Progress in Vanadium-based Cathode Materials for Aqueous Zinc Ion Batteries

水系锌离子电池(ZIBs)因其成本低、安全性高、锌资源丰富、环境友好等优点,被认为是锂离子电池的潜在替代品。与其他正极材料相比,钒基材料具有成本低、容量高、功率密度高、循环寿命长等优点而被认为是有前途的ZIBs正极材料,但低的固有电导率和充放电过程中不稳定的相变对其应用构成了巨大的挑战。综述了钒基正极在水系ZIBs中的最新研究进展。

Aqueous zinc-ion batteries(ZIBs)are considered as a potential alternative to lithium-ion batteries owing to their low cost,high safety,abundant zinc resources,and environmental friendliness.Compared with other cathode materials,vanadium-based materials are considered as promising cathode materials for ZIBs with the advantages of low cost,high capacity,high power density,and long cycle life,but the low intrinsic conductivity and unstable phase transition during charging and discharging pose great challenges for their applications.In this paper,the recent research progress of vanadium-based cathodes in aqueous ZIBs was reviewed.
