Title
(EN) Aluminum plate for aluminum electrolytic capacitor electrode, aluminum electrolytic capacitor, and process for producing aluminum electrolytic capacitor
(ZH) 铝电解电容器电极用铝板、铝电解电容器和铝电解电容器的制造方法
Abstract
(EN)
An aluminum plate (1) having an aluminum purity of not less than 99.98% by mass and an Fe content of 5 to 50 ppm with the balance consisting of unavoidable impurities is used to realize increased capacitance of an aluminum electrolytic capacitor, reduced height, and improved high frequency characteristics. In this aluminum plate (1), the total content of Fe in crystal/precipitate is 1 to 50% based on the original content, and the thickness of the aluminum plate is 0.2 to 1 mm. In the formation of a capacitor anode, the aluminum plate (1) is subjected to alternate current etching so as to leave a core part (2) having an average thickness of 50 to 150 [mu]m in the center part in the thickness-wise direction to increase the surface area, followed by anodic oxidation.

(ZH)

为了达到铝电解电容器的高容量化、低背化、高频特性提高的目的,使用由铝纯度为99.98质量%以上、Fe含有量为5~50ppm、和其余部分为不可避免的杂质所构成的铝板(1)。该铝板(1),结晶/析出物中的Fe的合计量为原含有量的1~50%,厚度为0.2~1mm。在形成电容器阳极时,以在厚度方向的中心部分余留平均厚度为50~150μm的芯部(2)的方式对铝板(1)进行交流蚀刻,扩大表面积后,进行阳极氧化。
