Method for manufacturing high-voltage solid-electrolyte aluminum electrolytic capacitor

A method for manufacturing a high-voltage solid electrolyte aluminum-electrolytic capacitor, comprising:

• (1) welding a capacitor core of a capacitor 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 for 1˜30 minutes;
• (3) removing the capacitor core out of the dispersion, creating a vacuum and then impregnating the capacitor core in the dispersion for 1˜10 minutes;
• (4) keeping the capacitor core in the dispersion, breaking the vacuum and then performing pressurization, and keeping the pressurized state for 1˜10 minutes;
• (5) keeping the capacitor core in the dispersion, 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 65˜100° C. temperature of and drying it for 20˜60 minutes, and then placing the capacitor core in a 135˜165° C. temperature of and drying it for 20˜60 minutes;
• (7) repeating steps (3) to (6) at least once;
• (8) putting the capacitor core in an aluminum cover and sealing it, and performing aging treatment to obtain a high-voltage solid electrolyte aluminum-electrolytic capacitor, wherein
• the dispersion A is a dispersion that comprises conductive polymers.
