ELECTROLYTIC CAPACITOR ELEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240296997 titled 'ELECTROLYTIC CAPACITOR ELEMENT

The abstract describes an electrolytic capacitor element with an anode, dielectric layer, mask layer, and cathode with a solid electrolyte layer and conductive layer.

  • Anode with front end face and base end face
  • Dielectric layer on main face of anode excluding base end face
  • Mask layer on dielectric layer near base end face
  • Cathode on front end face side of dielectric layer from mask layer
  • Cathode includes solid electrolyte layer and conductive layer
  • Solid electrolyte layer has two layers of conductive polymer doped with different dopants
  • Second layer of solid electrolyte layer partially disposed in the plane
  • Second conductive polymer more likely to be dedoped than first conductive polymer

Potential Applications: - Energy storage devices - Power electronics - Consumer electronics

Problems Solved: - Improved performance of electrolytic capacitors - Enhanced stability and reliability
