ないと含浸がスムーズに行なわれない。The purpose of preheating the winding element is to heat the element ``ti'' in the liquefied TCNQ salt.
This is to allow the TCNQ salt to smoothly enter the element P without lowering the temperature of the TCNQ salt during dipping and impregnation. If the device is cold, the TCNQ salt will not be sufficiently impregnated into the device. Therefore, the preheating temperature should be selected to be equal to or higher than the temperature of the liquefied TCNQ salt. Specifically, since the temperature Zf of liquefied TCNQ salt is around the melting point,
Impregnation cannot be carried out smoothly unless the element is preheated by about 20 degrees Celsius.

定ざｎなければならない。On the other hand, the carbonization of the separator paper is insufficient (change the weight 9096
above), the impregnation rate of TCNQ salt is significantly reduced. Since the separator paper loses its function when the weight R changes by 40% or less, the initial weight R change 'C is preferably 9096 to 4096. Therefore, the temperature and time for preheating the winding element must be determined in consideration of the degree of carbonization of the separator paper.

The case was heated and held on an iron plate. The same case will eventually become the capacitor's envelope. The melting point of the TCNQ salt is 210°C to 220°C, so the TCNQ salt in the case is melted and liquefied by the heating.

Q: Impregnated with salt. In the second step, the case is immediately immersed in water at room temperature to cool it down. Such cooling is performed as described above.
It should begin as soon as the liquefaction of the CNQ salt is complete. That is, if the TCNQ salt is kept in a liquid state for a long time, TCNQ salt
Q Salt foams violently and becomes a gas insulator. More specifically, the time from liquefaction to insulator is TC
The lower the liquefaction retention temperature of the NQ salt, the longer it will last, and when the temperature is 280°C to 290°C as described above, the cooling start time is set within about 4 minutes, preferably within 1 minute, after the liquefaction is completed. .

る。The following margins are shown in the table above. If the winding element is preheated and the separator paper is carbonized as in the example, the capacitance increases and t
It is clear that the effect of reducing anJ and EAR appears. Such an effect due to element preheating is due to the fact that the fibers of the separator paper become finer than 4 due to carbonization, and the solid [ This is due to the increased degree of solute impregnation and the total increase in recrystallized TCNQ salt.

にして当初の９０ｇ６〜４０ｓ６が好ましい。If the element preheating temperature is too high, only the fibers near the surface of the separator paper will be excessively carbonized, and the carbonization will not proceed sufficiently to the fibers inside n1. The treatment temperature for Sub-2 should be set at 400°C or lower, preferably 300°C or lower. Also, as is clear from Fig. 1, the longer the time (f), the more carbonization progresses.
Excessive carbonization leads to a decrease in electrical insulation and cracking of the separator paper, so the degree of carbonization is preferably 90g6 to 40s6 based on the initial weight of the separator paper.

にもＶ利でるる。(G) Effects of the Invention As is clear from the above explanation, according to the present invention, an anode foil and a foil are wound up with a separator paper in between, and an organic semiconductor made of TCNQ salt is applied to the separator paper as a solid electrolyte. Since the preheating of the winding element and the carbonization of the separator paper can be performed in the same process using a solid electrolytic capacitor impregnated as a solid electrolytic capacitor, there is no need to perform excessive carbonization, and the number of processes is reduced. The cost can be reduced by +1, and the V gain can be achieved in terms of economy as well.
