VO2·0.26H2O nanobelts@reduced graphene oxides as cathode materials for high-performance aqueous zinc ion batteries

A simple microwave-assisted hydrothermal approach is adopted to synthesize VO2·0.26H2O nanobelts@reduced graphene oxide (VO2·0.26H2O@rGO), which is regarded as a promising cathode material for ZIBs. Compared to VO2·0.26H2O, VO2·0.26H2O@rGO has a large specific surface area and low charge transfer re...

Zusammenfassung:A simple microwave-assisted hydrothermal approach is adopted to synthesize VO2·0.26H2O nanobelts@reduced graphene oxide (VO2·0.26H2O@rGO), which is regarded as a promising cathode material for ZIBs. Compared to VO2·0.26H2O, VO2·0.26H2O@rGO has a large specific surface area and low charge transfer resistance, improving its electrochemical properties. The large lattice spacing, high capacitive Zn2+ storage behavior, fast Zn2+ transfer rate and stable structure are also responsible for the performance.
