Abstract
Vanadium-based cathodes have received widespread attention in the field of aqueous zinc-ion batteries,presenting a promising prospect for stationary energy storage applications.However,the rapid capacity decay at low current densities has hampered their development.In particular,capacity stability at low current densities is a requisite in numerous practical applications,typically encompassing peak load reg-ulation of the electricity grid,household energy storage systems,and uninterrupted power supplies.Despite possessing notably high specific capacities,vanadium-based materials exhibit severe instability at low current densities.Moreover,the issue of stabilizing electrode reactions at these densities for vanadium-based materials has been explored insufficiently in existing research.This review aims to investigate the matter of stability in vanadium-based materials at low current densities by concentrating on the mechanisms of capacity fading and optimization strategies.It proposes a comprehensive approach that includes electrolyte optimization,electrode modulation,and electrochemical operational conditions.Finally,we presented several crucial prospects for advancing the practical development of vanadium-based aqueous zinc-ion batteries.
