| titleOfInvention | Preparation method of 150 ℃ high-temperature-resistant solid polymer aluminum electrolytic capacitor |
| abstract | The invention relates to a method for preparing a solid polymer aluminum electrolytic capacitor resistant to high temperature of 150 ℃, which comprises the steps of immersing a capacitor element with aluminum and a dielectric layer formed by an aluminum oxide film in a conductive polymer aqueous dispersion, taking out, drying and operating at least once to obtain a capacitor element with a conductive polymer layer; then soaking the capacitor element in a plant polyphenol aqueous solution, wherein the plant polyphenol in the plant polyphenol aqueous solution comprises at least one of flavonoid compounds, tannin compounds, anthocyanin compounds and phenolic acid compounds, taking out the capacitor element after soaking for at least 20 minutes, drying the capacitor element at 155-165 ℃ for 1-3 hours, and performing at least one operation to obtain a plant polyphenol self-polymerization protective film outside the conductive polymer layer; after the assembly, the solid polymer aluminum electrolytic capacitor which can resist the high temperature of 150 ℃ is prepared; the method can improve the high temperature resistance of the solid polymer aluminum electrolytic capacitor and reduce the leakage current. |
