Abstract:Electrolytic copper powder, with its distinctive physicochemical traits and unique dendritic configuration, is an indispensable fundamental material in high-end manufacturing and advanced material synthesis. However, the preparation of electrolytic copper powder through the modification of conventional process parameters confronts challenges including high energy consumption, diminished production efficiency, excessively coarse and bulky products, and narrow parametric control windows. The strategic application and optimization of additives in the electrolyte have emerged as a crucial strategy for improving the manufacturing process of electrolytic copper powder. These additives can efficiently regulate the electrochemical reaction process, modify the copper powder""s morphology, and enhance its performance. This review thoroughly discussed the roles of various additives - cationic, anionic, non-ionic, and amphoteric in the preparation of electrolytic copper powder, exploring the synergistic effect among them and its impact on the powder""s morphology and performance. Additionally, this review highlighted current challenges and emerging trends in applying these additives. The comprehensive analysis of the additives in this study could serve as a reference for selecting suitable additives, optimizing electrolysis processes, increasing product performance, and discovering new applications for electrolytic copper powder.
