摘      要：Exploring high-performance cathode materials for aqueous zinc ion batteries(ZIBs)is still one of the critical *** vanadate compound has become a potential cathode material for ZIBs with a novel displacement reaction mechanism of reversible reduction/oxidation of Cu^(2+)/Cu^(0).Herein,we reported Cu_(0.95)V_(2)O_(5)nanoflowers prepared using a hydrothermal synthesis method as a capable cathode material for *** Cu_(0.95)V_(2)O_(5)nanoflowers exhibit high specific capacity of 405 mAh·g^(-1) at the current density of 100 mA·g^(-1),benefiting from the displacement reaction mechanism and phase transformation mechanism from Cu_(0.95)V_(2)O_(5)to the open and stable architecture Cu_(0.4)V_(2)O_(5)and Zn3(OH)2V2O7·2H2O *** cathode exhibits excellent rate performance with a high capacity of-200 mAh·g^(-1)at 5 A·g^(-1) and outstanding cycle stability with a capacity retention of 92%after 1000 *** is anticipated that the novel Cu_(0.95)V_(2)O_(5)nanoflowers are promising cathode material in the application for zinc ion batteries.
