Abstract

The migration and deposition behavior of ions is a critical step in the electrolytic deposition process and plays an important role in determining the mass transfer rate, crystal size, morphology and purity. Understanding the migration and deposition behavior of ions is therefore important to achieve controllability of desired electrodeposited products. In this paper, we first outline the relevant theoretical foundations, including mass transfer, boundary layer, and double electric layer theories. Subsequently, we summarize recent research advances in ion diffusion, convection, electromigration, and inter-ion and ion-solvent interactions, and discuss the mechanisms of crystal formation, growth, and dendrite inhibition. Finally, the effects of ion migration and deposition behavior on deposition quality are analyzed, and challenges, opportunities and future research directions in this field are discussed. This study provides an important reference for optimizing the electrolytic deposition process and developing high-performance electrodeposited materials.

电解过程中金属离子的迁移和沉积行为

离子的迁移和沉积行为是电解沉积过程中的关键步骤，对决定传质速率、晶体尺寸、形貌和纯度起着重要作用。因此，了解离子的迁移和沉积行为对于实现所需电沉积产物的可控性非常重要。本文首先概述了相关的理论基础，包括传质理论、边界层理论和双电层理论。随后，我们总结了近年来在离子扩散、对流、电迁移、相互作用和离子-溶剂相互作用方面的研究进展，并讨论了晶体形成、生长和枝晶抑制的机制。最后，分析了离子迁移和沉积行为对沉积质量的影响，并讨论了该领域面临的挑战、机遇和未来的研究方向。该研究为优化电沉积工艺和开发高性能电沉积材料提供了重要参考。
