AB - Rechargeable aqueous zinc-ion batteries (ZIBs) have been gradually attracting attention, because they are inexpensive and abundant; thus, they are favorable choice for energy storage system. Layered vanadium oxides have excellent zinc-ion storage capacity; however, significant challenges, such as poor conductivity and slow zinc-ion intercalation/deintercalation reaction, remain. Herein, we fabricated a material comprising V2O5 and Ag (Ag0.3V2O5, AVO) with a high conductivity and stable structure. Using this strategy, the ZIBs based on the AVO electrode achieved a high capacity of 340 mAh g−1 at 0.10 A g−1, long-term cyclic stability with over 93.75% retention after 1600 cycles and a nice rate performance (135 mAh g−1 at 2.0 A g−1). The nanowire structure was hardly corroded after the reaction. These results indicate that Ag+ can become “pillars” for V2O5, thereby improving the stability of the material. Moreover, Ag+ is involved in the reaction of aqueous zinc-ion batteries; thus, the cyclic performance and battery capacity are improved.
