As the demand for energy-storage devices in electronics such as wearable devices and flexible displays, safe rechargeable batteries have attracted energy-related industries. Especially, aqueous zinc (Zn) batteries are one of most promising candidates for large-scale energy storage devices due to their many 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, I will present the design of carbon-based polymer composite for a highly reversible aqueous Zn battery by stabilizing the Zn surface during the plating/stripping.
