▎ 摘 要
A simple microwave-assisted hydrothermal approach is adopted to synthesize VO2 center dot 0.26H(2)O nanobelts@reduced graphene oxide (VO2 center dot 0.26H(2)O@rGO), which is regarded as a promising cathode material for ZIBs. Compared to VO2 center dot 0.26H(2)O, VO2 center dot 0.26H(2)O@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.
