Abstract
The present invention discloses a method for manufacturing a high-voltage solid electrolyte aluminum-electrolytic capacitor, including: (1) Welding a capacitor core onto an iron bar, applying a voltage for chemical treatment, and after the chemical treatment, washing and drying the capacitor core; (2) impregnating the dried capacitor core in a dispersion A for 1˜30 minutes; (3) removing the capacitor core out of the dispersion A, creating a vacuum and then impregnating the capacitor core in the dispersion A for 1˜10 minutes; (4) keeping the capacitor core in the dispersion A, breaking the vacuum and then performing pressurization, and keeping the pressurized state for 1˜10 minutes; (5) keeping the capacitor core in the dispersion A, performing depressurization to an atmospheric pressure, and keeping the atmospheric pressure for 1˜10 minutes; (6) taking the capacitor core out, placing the capacitor core in a temperature of 65˜100° C. and drying it for 20˜60 minutes, and then placing the capacitor core in a temperature of 135˜165° C. and drying it for 20˜60 minutes; (7) repeating steps (3) to (6) at least once; and (8) putting the capacitor core in an aluminum cover and sealing it, a…
