Title:
A CAPACITOR AND METHOD OF ITS MANUFACTURING BASED ON AN OXIDATIVE POLYMERIZATION DISPERSION
Document Type and Number:
WIPO Patent Application WO/2024/015221
Kind Code:
A3
Abstract:
An improved dispersion, which is particularly suitable for use in forming a hybrid capacitor, and improved method for forming a hybrid capacitor, and an improved capacitor is provided. The method comprises forming a dispersion comprising a conductive polymer, a dispersing agent, a monomer of the conductive polymer and a molar excess of anionic counterion per mole of conductive polymer and monomer. The dispersion is homogenized to form a homogenized dispersion. A capacitor is formed comprising a conductive layer formed from the homogenized dispersion.
