摘要
对近年来微量金属离子在铝电解电容器用电极箔扩面腐蚀工艺的最新研究成果进行了总结,在铝箔腐蚀过程中,金属离子能与铝形成电偶腐蚀,在铝箔表面指引点蚀生长,使铝箔的腐蚀电位负移,孔密度增大,并孔减少,比电容增大。讨论了它们各自的技术优势和短板,展望了今后微量金属离子对电极箔扩面腐蚀技术在性能及机理研究方面的趋势。
The recent advances in research of effects of trace metal ions on surface area extending for etched aluminum foil were summarized.The galvanic corrosion occurring between metal ions and Al during the etching of aluminum foil guided the pitting on the aluminum foil surface and results in a negative shift of corrosion potential,an increase of pitting density,and a reduction of merged tunnels,hence increasing the specific capacitance.The advantages and disadvantages of each electroless plating process were discussed.The development trends of the research on performance and mechanism of effects of of trace metal ions on surface area extending for etched aluminum foil were summarized in the future were prospected.
