| Abstract Scope |
This study proposes a Zn–Ag binary alloy anode material for use in high-stability aqueous zinc-ion batteries. Guided by thermodynamic phase diagrams, the alloy composition was carefully designed and followed by post-casting heat treatment to precisely control the microstructure and phase distribution of the material. This approach significantly enhances electrical conductivity and ensures uniform zinc deposition. Experimental results demonstrate that the Zn–Ag composite anode exhibits excellent dendrite suppression during charge–discharge cycling, effectively preventing internal short circuits and capacity fading caused by dendrite growth. In long-term electrochemical cycling tests, the composite anode shows good stability and reproducibility, with a significantly longer cycle life compared to conventional pure zinc anodes. Overall, this work demonstrates that a simple melt-casting and heat treatment strategy can produce dendrite-free, long-life, and high-safety zinc anodes, offering a concrete direction for the design and fabrication of future zinc-ion battery materials. |
