Recent Progress on the Intercalation Strategies of Vanadium-Based Material Cathodes for Aqueous Zinc-Ion Batteries

Aqueous zinc-ion batteries (AZIBs) are widely regarded as promising alternatives to lithium-ion batteries (LIBs) due to their high theoretical capacity, cost-effectiveness, and environmental friendliness features. The crucial factor in the development of high-performance AZIBs is to explore cathode materials that match with zinc anode. Vanadium-based materials are widely utilized as cathode materials. However, their development is also hindered by slow transfer kinetics, vanadium dissolution, poor electrical conductivity, etc. Herein, the research progress on ion doping of vanadium-based materials in high-performance AZIBs is summarized. It includes the challenges faced by vanadium-based materials, the energy storage mechanisms, and the intrinsic effects of ion doping-modified electrode materials. Moreover, their perspectives on ZIBs are also proposed.
