Abstract

Aqueous zinc-ion batteries have broad application prospects due to the eco-friendliness, cost-economy and high safety. However, the scarcity of high-performance cathodes with outstanding rate capability and long lifespan has affected their development. Herein, we report a metallic vanadium trioxide material intercalated with phase transformation as cathode applied in aqueous zinc-ion batteries. It offers satisfactory electrochemical performances with a high specific capacity (435 mAh g⁻¹ at 0.5 A g⁻¹), decent power density (5.23 kW kg⁻¹) and desired energy density (331 Wh kg⁻¹), as well as good cyclability. The superior performance originates from the stable structure and fast Zn²⁺ diffusion, enabled by the pre-intercalation of Zn²⁺ and water molecules.
