Because of their low cost, safety, and green nature, aqueous zinc-ion batteries (AZIBs) have become attractive energy storage devices. However, problems such as zinc dendrites have been hindering the development of AZIBs. In this paper, two materials polyacrylamide (PAM) and polypropylene (PAN) are used to modify the surface of the zinc. The experimental results show that the coating of the two organic membranes can effectively improve the electrochemical performance of the AZIBs. Symmetric Zn/PAM||Zn/PAM and Zn/PAN||Zn/PAN cells can steadily work over 12000 min at 0.5 mA cm −2 , which are greater than that of bare Zn||Zn. At 0.2C multiplicity, the full cells with the zinc modified by both materials as negative electrode exhibited a stable cycle retention rate close to 40% of the initial value after 100 cycles.
