Abstract
The electrolyte is composed of a complex salt of 7,7,8,8-tetracyanoquinodimethane(TCNQ) and a nitrogen-containing polymer capable of dissolving the salt. The capacitor characteristics are largely affected by both the molecular weight and the amount of the polymer, and the capacitor of improved characteristics is provided by the use of the polymer of a mean molecular weight between 2,000 and 200,000 in an amount between 2 and 10% by weight of the TCNQ salt.
