摘要：
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.
