The development of high-performance cathode material is the key to realize commercial application of zinc-ion batteries (ZIBs). Vanadium-based materials have been used as cathode candidate for ZIBs due to their...
Ca2+-Intercalated hydrated V2O5/rGO (CaVOH/rGO) is synthesized via a facile hydrothermal process and applied as a cathode for ARZIBs with an admirable specific capacity (409 mA h g−1 at 0.05 A g−1) and excellent energy density (381 W h kg−1).
