Abstract:
1. An electrolyte capacitor produced with the process which comprises applying a dispersion A) on to a porous body wherein said porous body comprises a porous electrode body of an electrode material and a dielectric which covers the surface of the electrode material, wherein said dispersion A) is directly applied onto the dielectric surface wherein the dispersion comprises at least particles B) of an electrically conductive polymer and a dispersing agent D), and and for the formation of a solid electrolyte which completely or partly covers the dielectric surface, the dispersing agent D) is at least partly removed and/or cured, wherein the viscosity of dispersion A) can be between 0.1 and 500 mPas (measured at 20° C. and a shear rate of 100 s −1 ), wherein the particles B) of the conductive polymer in the dispersion A) have an average diameter of 5 to 40 nm, and films produced from particles B) have a specific conductivity in the dry state of greater than 10 S/cm and wherein the particles B) of the conductive polymer in the dispersion A) have d 10 value of the diameter distribution of greater than 5 nm, wherein the d10 value of the diameter distribution states that 10% of the total weight of all the particles B) of the conductive polymer in the dispersion A) can be assigned to those particles B) which have a diameter of less than or equal to the d10 value and have d 90 value of the diameter distribution of less than 50 nm, wherein the d90 value of the diameter distribution states that 90% of the total weight of all the particles B) of the conductive polymer in the dispersion A) can be assigned to those particles B) which have a diameter of less than or equal to the d90 value.
