| titleOfInvention | Method for manufacturing electrode foil for solid aluminum electrolytic capacitor |
| abstract | The invention relates to a method for manufacturing an electrode foil for a solid-state aluminum electrolytic capacitor, which comprises two parts of corrosion and formation, wherein the corrosion part comprises the following steps: pretreating the electronic optical foil in a hydrochloric acid solution; adding a mixed solution of hydrochloric acid and sulfuric acid to perform galvanic pore corrosion; reaming, electrifying, corroding, cleaning and soaking; washing with tap water, and annealing to obtain the corrosion foil for the solid aluminum electrolytic capacitor, wherein the formation part comprises: boiling the solid aluminum electrolytic capacitor with corrosion foil; performing primary electrochemical anodic oxidation and primary annealing heat treatment; carrying out secondary annealing heat treatment after secondary electrochemical anodic oxidation and tertiary electrochemical anodic oxidation; carrying out three times of annealing heat treatment after four-level electrochemical anodic oxidation; soaking in phosphoric acid, soaking in ammonium dihydrogen phosphate, cleaning, and drying; an electrode foil for a solid aluminum electrolytic capacitor was obtained. The invention can effectively reduce the disturbance of the current at the tip, reduce the generation of invalid pinholes in the corrosion process and improve the capacity extraction rate of the solid foil; effectively improve the quality of the oxide film, keep the stability and effectively improve the high-temperature stability of the solid capacitor. |
