摘要
现有制备工艺制造出的电解铜箔材料储锂性能差,因此设计一个电解铜箔材料的电化学制备方法。溶铜时在专业的容器内采用逆向通风喷淋的方法,升高氧压力,提高硫酸的浓度;确定电流密度、电解液温度、铜离子浓度、H2SO4浓度和流量参数,选择含有亲水基与疏水基的添加剂保证电解铜箔的表面平整性与光亮性,完成电解铜箔材料的电化学制备方法的研究。
The electrolytic copper foil material produced by the existing preparation process has poor lithium storage performance,so an electrochemical preparation method of electrolytic copper foil material is designed.When copper is dissolved,reverse venting is used in a professional container to increase the oxygen pressure and increase the concentration of sulfuric acid;determine the current density,electrolyte temperature,copper ion concentration,H2SO4 concentration and flow parameters,and select the hydrophilic group and The hydrophobic base additive ensures the surface flatness and brightness of the electrolytic copper foil,and completes the electrochemical preparation method of the electrolytic copper foil material.
