Abstract:
Up to 0.61 V increase of the working potential was achieved by modifying the anthraquinone (AQ) molecular structure with a stronger electron-withdrawing cyano group. Owing to the promoted discharge potential, an attractive energy density of 151.9 W h kg-1 was realized for the Zn//TCNAQ full cell. The TCNAQ also displayed a good capacity retention of 81% after 1000 cycles at 500 mA g-1 and a high mass loading practicability. Our research provided insight into the design of organic cathode materials with a tailored working potential for aqueous Zn-ion batteries.

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,...
