1) (where k: constant, d: thickness of TCNQ salt, S: electrode area) Therefore, when considering the resistance R1 and the equivalent series resistance,
The value of S in equation (1) must be considered. Therefore, conventionally, the separator has a low density of about 0.35 (g, /
By using manila paper with a size of 2 cm"), the impregnation rate of the TCNQ salt into the separator, that is, the filling rate between the electrodes was increased, thereby increasing the electrode area of the TCNQ salt and reducing the resistance. However, since Manila paper is made of short fibers, as the density is reduced or carbonized, the bonding force between the fibers weakens, resulting in a structure with uneven fiber distribution.
Capacitors impregnated with CNQ salt have a high rate of occurrence of short circuits between electrodes, which has the drawback of deteriorating leakage current characteristics. In the present invention, the density is 0.30-0.50.
This problem was solved by using a double layer of electrolytic paper made of (g/cm') low-density tubular hemp and esparto, which strengthened the strength of the separator paper and reduced leakage current. This provides a stable capacitor.

The values of can be considered to be almost equal. In addition, regarding the electrode area (S), since TCNQ salt is impregnated with electrolytic paper of the same density, the difference between the inventive product and the conventional product is small and can be ignored), and overall it is almost the same as the conventional product. It is assumed that it is at the level. Therefore, it is thought that the equivalent series resistance will also be approximately at the conventional level.
