Rechargeable aqueous zinc ion batteries are highly attractive system for next generation energy storage devices because of their intrinsic safety, sustainability, low cost, and high energy density from two-electron process. Recent studies adopt organic molecules for the active materials to resolve solubility problems of inorganic electrode, yet electrode dissolution is still occurred due to the structure change of organic molecules during the cycling. Herein, we firstly used 1,4,5,8-naphthalene diimide (NDI) for the active materials of aqueous zinc ion batteries. Combined analysis based on electrochemical measurement and spectroscopic method revealed the importance of electrolyte environment for determining its structural stability and battery performance. Through the analysis on NDI molecule, we tried to understand the reaction mechanisms of the organic molecules for the further designing of high-performance organic electrodes. |
