Zinc-based energy storage technologies have advanced considerably, driven by their abundance, cost-effectiveness, low redox potential, safety, and superior specific volumetric capacity compared to other metal-based batteries. Despite these advantages, their practical application is hindered by challenges such as Zn dendrite formation, corrosion, and hydrogen evolution side reactions. These problems reduce reversibility and cause mechanical damage, ultimately affecting the long-term performance and durability of zinc anodes in rechargeable batteries. The inherent roughness of Zn and surface damage during fabrication of the Zn foil surface creates uneven distributions of the electric field and Zn²⁺ ion concentrations, initiating side reactions and dendrite formation. These issues intensify surface defects, perpetuating a cycle of continuous degradation. Moreover, excessive dendrite growth during Zn plating can produce protrusions that puncture separators, leading to potential short circuits in battery cells, reducing overall lifetime. Here, a novel method is introduced for modifying interfacial properties on Zn anodes by depositing a submonolayer of nanoparticles (NPs) arrays using reverse micelle templating (RMD). Reverse micelle synthesis offers a straightforward solution-based process that accommodates a wide range of ionic metal salts for nanoparticle synthesis. Additionally, this approach enables precise control over nanoparticle size and facilitates the formation of uniformly dispersed 2D arrays under varying conditions, resulting in highly tunable nanoparticles. In this study, we successfully synthesized Gold (Au), Tin Oxide (SnOx), and Tin-Gold (SnAu) nanoparticles (NPs), which were then deposited on Zn anode surface to compare anode stability with the formation of nanoparticle submonolayers. Cycling performance was evaluated in symmetric coin cells. Both Au and SnOx NPs significantly extended the lifetime of symmetric cells, whereas SnAu NPs exhibited extremely unstable cycling performance. Among the tested NPs, Au NPs exhibited the best cycling performance with the lowest overpotentials. Further investigation of Au NPs modified An Zn anode including chronoamperometry, Impedance spectroscopy (EIS) and SEM micrographs revealed that Au NPs reduced Zn diffusion on the surface, enhanced charge transfer kinetics and homogeneous plating compared to the bare Zn anode, resulting in improved cycling stability in symmetric cells. Additionally, density functional theory (DFT) calculations showed that the adsorption energies and diffusion barriers confirmed the zincophilic nature of Au NPs, which effectively regulated Zn diffusion and facilitated uniform nucleation. This approach offers a novel strategy for surface engineering of Zn anodes to enhance battery stability. Figure 1
