Abstract
A method for impregnating electrolytic capacitors by a tetracyanoquinodimethane (TCNQ) salt is disclosed. The method consists in introducing TCNQ salt into the capacitors by electrolytic means, with a solution consisting of a solvent, wherein TCNQ has been dissolved and which contains a support electrolyte, the cation of the support electrolyte and the dissolved TCNQ leading, after electrolytic dissociation, to said TCNQ salt. The method can be applied to the manufacture of aluminum electrolytic capacitors with solid electrolyte.
