Abstract

In this paper, it is proposed that a TiO₂-Al₂O₃ composite powder-layer aluminum foil (denoted as CPLAF) with high specific volume was prepared by aluminum powder additive method combined with sol–gel deposition valve metal. The results show that the unit specific capacitance of CPLAF is 1.196 μF∙cm⁻² at a formation voltage of 520 V, which is significantly higher than that of powder-layered aluminum foils (denoted PLAF) without deposited TiO₂, and has better electrical performance advantages than those reported in the existing literature. This study provides a new way to improve the unit specific capacitance of anode foil of aluminum electrolytic capacitors.

高比电容TiO2-Al2O3复合粉末层状阳极铝箔的制备及性能

本文提出采用铝粉添加法结合溶胶-凝胶沉积阀金属制备高比容TiO2-Al2O3复合粉末层铝箔（CPLAF）。结果表明：在形成电压为520 V时，CPLAF的单位比电容为1.196 μF∙cm−2，明显高于未沉积TiO2的粉末层状铝箔（以下称PLAF），且具有比现有文献报道的更好的电性能优势。本研究为提高铝电解电容器阳极箔的单位比电容提供了一条新的途径。
