Abstract
Aqueous Zn-ion batteries (ZIBs) have received increasing attention because of their high safety, low cost and environmental benignity. However, the development of high-performance cathode materials using for zinc-ion de/intercalation is still a challenge. In this work, V2O5@polyaniline (V2O5@PANI) nanocomposites were synthesized by the polymerization of aniline and V2O5. Due to the organic-inorganic compatibility, V2O5@PANI exhibits a good electrochemical performance serving as cathode material for ZIBs, which displays a high specific capacity (361 mAh g−1 at 0.1 A g−1) and an excellent cycling stability (93.8% capacity retention after 1000 cycles).
