Title:
ALUMINUM ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2018/107813
Kind Code:
A1
Abstract:
Provided is an aluminum electrolytic capacitor, comprising an outer shell (1), an inner shell (2), a sealing material (3) and a core (4). The sealing material (3) is put into the inner shell (2) to form a seal, and the inner shell (2) and the outer shell (1) are assembled in an associated manner. The core (4) is disposed inside the inner shell (2) and comprises an electrolytic paper (401), a positive electrode foil piece (402), a negative electrode foil piece (403), a positive lead wire (404) and a negative lead wire (405). One side of the positive electrode foil piece (402) and one side of the negative electrode foil piece (403) are respectively connected to the electrolytic paper (401). The positive lead wire (404) is fixed on the other side of the positive electrode foil piece (402), and the negative lead wire (405) is fixed on the other side of the negative electrode foil piece (403). Surface-extended and capacity-increased micropores are formed on the surface of the negative lead wire (405) to form an oxide film. Sparkover breakdown of the capacitor during use is avoided, thereby obviously improving the stability and service life of the capacitor.
