Aqueous zinc (Zn) batteries are one of the promising candidates for next-generation batteries due to numerous advantages such as high air stability, cost-efficiency, resource availability, pro-environment, and reversibility. Despite these advantages in the rechargeable battery, the unstable Zn anode of irregular dendrite formation on the surface is the obstacle to achieving the stable charge/discharge process in aqueous Zn batteries. Herein, we design a highly reversible aqueous Zn battery by stabilizing the Zn surface during the charge/discharge process with poly(acrylic acid) (PAA) coating. The optimized PAA layer on the surface of Zn can effectively suppress the dendrite formation, and the carboxylic acid of PAA in electrolytes modulate the Zn deposition rate. This study indicates that the polymer-based coating layers have a high potential for utilizing practical aqueous Zn batteries.
