Abstract:
Cathode materials with both high capacity and high operating voltage are essential for advancing aqueous zinc-ion batteries (ZIBs). Conventional high-capacity materials, such as vanadium-based compounds, typically deliver low discharge voltages. In contrast, organic cathodes show high operating voltages but often exhibit limited capacity. The present study focuses on developing hybrid cathodes composed of organic (amino PEG amine, APA) and inorganic (ammonium vanadium oxide, NVO) components, referred to as APA-NVO, featuring a dual energy-storage mechanism specifically designed to achieve a wide operating voltage of 1.9 V and provide exceptionally durable ZIBs.

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,...
