摘　　要：最佳孔径和孔密度工艺开发是研发及制备高容量电子铝箔的重要环节。以孔分布均匀、孔径、孔深相等及孔径无衰减为假设前提条件,建立孔径和孔密度模型,归纳出各化成电压下,理论面积最大(容量最高)对应的孔径和孔密度,并对比了各孔径对应的面积(容量)衰减率。同时还对影响孔径和孔密度以及孔分布的生产加工机理进行了分析。在实际生产中针对不同化成电压,围绕孔径和孔密度,可参考蚀孔理论模型和实测的腐蚀率,按不同化成电压分别优化光箔和腐蚀工艺,达到最大限度提高电极箔容量的目的。In order to produce high-capacity electronic aluminum foil, it is necessary to develop the relevant processing technology around the optimal corrosion pit diameter and pit density. This paper simulates the pit size and pit density model on the assumption that the pit distribution is uniform, the pit spacing is equal to the pit diameter, the hole depth is the same, and the pit diameter has no attenuation, and summarizes the corresponding pit diameter and pit density that can reach the maximum theoretical area(the highest capacity) under each forming voltage;the calculation results of the surface area(capacity) attenuation law corresponding to each voltage and pit diameter are given;the factors affecting the pore diameter, pore density and pore distribution in production are discussed. In actual production, different forming voltages have different control corrosion points on pit diameter and pit density. According to the theoretical model of etching and the measured corrosion rate, the etching process can be optimized according to different formation voltages to maximize the capacity of electrode foil.
