[目的]添加剂的选择和复配及其对镀液性能的影响是锂电铜箔制备过程中的关键技术问题。[方法]在硫酸盐体系电解液中分别添加Cl~-、DPS(N,N-二甲基-二硫代羰基丙烷磺酸钠)、SPS(聚二硫二丙烷磺酸钠)、蛋白肽、PEG 6000(聚乙二醇)和OP-10(十二烷基酚聚氧乙烯醚乳化剂)添加剂，采用阴极线性扫描伏安法(LSV)研究各自对铜电沉积行为的影响。[结果]Cl~-和DPS对铜离子的还原具有明显的促进作用，蛋白肽、PEG 6000和OP-10抑制铜离子还原，SPS与Cl~-协同作用时可促进铜离子还原。[结论]阴极线性扫描伏安法可快速评估添加剂的作用效果，为锂电铜箔生产中添加剂的筛选与复配提供有效指导。
Abstract：[Objective] The selection and formulation of additives, along with their effects on properties of electrolyte,are critical technical challenges in the production of lithium battery copper foil. [Method] Different additives, including Cl~-, DPS(sodium N,N-dimethyldithiocarbamoylpropyl sulfonate), SPS [sodium bis(3-sulfopropyl) disulfide], protein peptide, PEG 6000(polyethylene glycol), and OP-10(polyoxyethylene lauryl phenyl ether), were respectively added to a sulfate-based electrolyte, and their effects on electrodeposition behavior of copper were studied by cathodic linear sweep voltammetry(LSV). [Result] Both Cl~-and DPS could significantly promote the reduction of copper ion, while protein peptide, PEG 6000, and OP-10 inhibited the reduction of copper ion. Additionally, SPS exhibited a synergistic effect with Cl~-to enhance the reduction of copper. [Conclusion] Cathodic linear sweep voltammetry serves as an efficient method to evaluate the effects of additives, providing valuable guidance for the selection and optimization of additives in production of lithium battery copper foil.
