摘　　要：高纯铝箔在15wt%盐酸、1wt%硫酸的混合溶液中,采用电化学腐蚀的方法,提高铝箔比表面积,使其容量大幅提升,满足固态铝电解电容器的应用要求。结果表明:反应温度为30℃、电流密度为0.6A/cm^2的条件下,电流最佳频率为36Hz;同时,阳极箔在经过纯水浸泡处理后,热处理温度设定为500℃,铝氧化膜晶型结构最优。In the mixed solution of 15wt%hydrochloric acid and 1wt%sulfuric acid,high purity aluminum foil uses the method of electrochemical corrosion to increase the specific surface area and capacity of aluminum foil,which can meet the application re-quirements of solid-state aluminum electrolytic capacitors.The results show that the optimum current frequency is 36Hz when the re-action temperature is 30℃and the current density is 0.6A/cm^2,and the crystal structure of aluminum oxide film is the best when the anode foil is immersed in pure water and the heat treatment temperature is set at 500℃.
