“…The X-ray diffraction (XRD) analysis confirms the successful deposition of AlN with low crystallinity (Figure a). , It is interesting to note that the AlN in the AlN/Ag coating is amorphous, given the significantly reduced peaks as compared to the baseline. This can be explained by the fact that the diffusion energy of Ag nanoparticles and AlN molecules on the Zn foil surface is decreased due to the collision among Ag, AlN, and Ar/Ar + during the sputtering process, which inhibits the growth of AlN and Ag crystals and consequently promotes the even distribution of Ag in the AlN matrix (Figure a). , X-ray photoelectron spectroscopy (XPS) was then employed to probe the surface chemical states of AlN and AlN/Ag coatings (Figure S2). The strong Al 2p and N 1s peaks of AlN located at 74.2 and 397.2 eV, respectively, are attributed to the Al–N bonds .…”

Secondary aqueous zinc-ion batteries (ZIBs) are considered as one of the promising energy storage devices, but their widespread application is limited by the Zn dendrite issues. In this work, we propose a rational design of surface protective coatings to solve this problem. Specifically, a silver (Ag) nanoparticle embedded amorphous AlN matrix (AlN/Ag) protective layer is developed. The former would alloy in situ with Zn to form AgZn3 alloy sites, which subsequently induce the Zn deposition with preferred (002) facets. The latter can effectively alleviate the structural expansion during repeated Zn plating/stripping. Consequently, the delicately designed AlN/Ag@Zn anode delivers an enhanced stability with a long lifespan of more than 2600 h at 1 mA cm–2 and 1 mAh cm–2. Moreover, the AlN/Ag@Zn||Mn1.4V10O24·nH2O full batteries can be operated for over 8000 cycles under 5 A g–1. Our work not only suggests a promising Zn anode protective coating but also provides a general strategy for the rational design of surface protective layers for metal anodes.
