Modulating the Hydrogen Bond for a Stable Zinc Anode with a Wide Temperature Range via the Sucrose and Polyacrylamide Synergistic Effect

Zinc-ion batteries become a major research focus in energy storage, valued for their low cost and high safety. However, their widespread application is hindered by poor zinc anode stability caused by dendrites, side reactions, and poor performance across a wide temperature range at a strong hydrogen bond network aqueous electrolyte. In this study, we propose a strategy for the synergistic combination of a polyacrylamide hydrogel with sucrose. The experimental and theoretical results demonstrate that through the synergistic effect of the polyacrylamide hydrogel and sucrose, they regulate the solvation structure of Zn2+ and the hydrogen bond network and inhibit the interfacial side reactions caused by active…
