Abstract:
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.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
