Herein, we demonstrate that layered VSe 2 with a large interlayer spacing could exhibit excellent Zn storage behavior. Even with a micro-sized morphology, it exhibits a high specific reversible capacity of 250. 6 mA h g −1 at 200 and 5000 mA g −1 and good cycle life. . The realizing of high-performance rechargeable aqueous zinc-ion batteries (ZIBs) with high energy density and long cycling life is promising but still challenging due to the lack of suitable layered cathode materials. The work reports the excellent zinc-ion storage performance as-observed in. . Exploring electrode materials with high capacity, durability and fast Zn 2+ ion diffusion is crucial to address the aforementioned challenges.
