阀金属化合物在高比容铝电解电容器中的研究进展

To meet the development trend of functionalization and miniaturization of electronic products in recent decades, aluminum electrolytic capacitors are facing the same trend to achieve miniaturization and high electrical properties. One of the most effective ways to make it actualize is the preparation of high specific capacitance anode foil. This review systematically introduces the deposition techniques for the preparation of valve metal compounds for aluminum electrolytic capacitors. From the perspective of the film quality prepared by different deposition techniques, we expand the advantages and disadvantages of the various deposition techniques when preparing the anode composite foil for aluminum electrolytic capacitors. Further, the research progress of increasing the electric performance of anode foil by compositing a valve metal thin film was analyzed. Accordingly, several outlooks for promoting the practical applications of high specific capacitance aluminum electrolytic capacitors were proposed.
