Abstract

V₆O₁₃ with a nanosheet structure was employed as a cathode material for aqueous zinc metal batteries. V₆O₁₃ delivered a high specific capacity of 425 mA h g^-1, outstanding rate performance and durable cycling with high capacity retention of 86% after 3000 cycles. Moreover, in situ X-ray diffractometer (XRD), ex situ X-ray photoelectron spectroscopy (XPS) and X-ray absorption near-edge structure (XANES) were employed to ascertain the reaction mechanism of Zn²⁺ storage.
