| titleOfInvention | Method for improving specific volume of an aluminum electrode foil by electrochemical deposition method |
| abstract | The invention relates to an aluminum electrolytic capacitor, in particular to a method for improving specific volume of an aluminum electrode foil by an electrochemical deposition method. In the invention, an Al2O3/TiO2 composite dielectric film is prepared on the surface of the electrode foil by adopting a cathodic electrochemical deposition technology. The preparation process of the composite dielectric film comprises the following steps: taking metallic titanium as an anode, taking an aluminum etched foil as a cathode, and carrying out electro-deposition in an organic solvent-acetone containing halogen-iodine; depositing a titanium-containing compound layer on the surface of the etched foil, and then carrying out heat treatment; and finally carrying out anodic oxidation treatment so as to obtain the aluminum-titanium composite dielectric film with high dielectric constant on the surface of the etched foil. Compared with the traditional dielectric film, the composite dielectric film on the surface of the aluminum electrode foil obtained by the technological process has higher dielectric constant under the condition of equal thickness so as to more effectively improve the specific capacity of the aluminum electrode foil. The method has the advantages of simple process and lower cost, and is convenient for operation and easy to control. |
