No. 3, there is proposed an organic electrolyte battery in which an organic semiconductor having a polyacene skeleton structure is used as a positive electrode and a negative electrode, and an aprotic organic solvent solution is used as an electrolytic solution. Also, the material of the gasket that holds the insulation of the positive and negative electrode cans is extremely important. Conventionally, as a gasket material, polypropylene has been used, which has excellent chemical resistance, elasticity, and creep resistance, has good moldability, and is injection-moldable and inexpensive. The positive and negative electrode cans, separators, organic semiconductors having a polyacene-based skeleton structure and electrolytic solution of the battery have high melting points or boiling points and excellent heat resistance. However, the polypropylene used for the gasket has a low heat resistance temperature, and thus the conventional battery has a drawback that the heat resistance is inferior.

It has become difficult to secure a gap for inserting a soldering iron because of soldering. Therefore, apply solder to the part to be soldered on the printed circuit board in advance and place parts on that part,
Alternatively, after the parts are placed, the solder globules are supplied to the soldered portion, and the soldered portion is equal to or higher than the melting point of the solder, for example, 20
A method is used in which a solder is melted by melting a solder by passing a printed circuit board on which components are mounted in a furnace in a high temperature atmosphere set to 0 to 230 ° C. (hereinafter referred to as reflow soldering). ). In the conventional coin-type (button-type) organic electrolyte battery using a gasket made of polypropylene, polypropylene is melted or deformed during reflow soldering, and the positive and negative electrode cans made of stainless steel or aluminum come into contact with each other to cause a short circuit. there were.

池の耐熱性は改善されない。The polyamide resin in the present invention is generally referred to as a nylon resin, and has an amide bond --CO in the main chain.
It is a polymer having —NH—. Typically, it is a resin synthesized by polycondensation of dicarboxylic acid and diamine, polycondensation of ω-aminocarboxylic acid, or ring-opening polymerization of lactam, and the resin not only has excellent heat resistance but also chemical resistance. Excellent in moldability, creep resistance and elasticity, good in moldability, injection moldable and inexpensive, and suitable for battery gaskets. Of these, nylon 46 is more preferable in terms of heat resistance. The organic semiconductor having a polyacene skeleton structure used for the positive electrode and / or the negative electrode is manufactured by a thermal condensation polymerization reaction and has excellent heat resistance. Stainless steel or aluminum used for the positive electrode can or the negative electrode can is a metal having excellent heat resistance. The glass fiber nonwoven fabric preferably used for the separator has a high melting point of glass and is excellent in heat resistance. An aprotic organic solvent used as a solvent for the electrolytic solution, for example, propylene carbonate, has a high boiling point, and is significantly superior in heat resistance to the electrolytic solution used for an aqueous battery. Therefore, the heat resistance of the battery of the present invention was improved by using a polyamide resin having excellent heat resistance for the gasket having the lowest heat resistance. In other batteries, for example, an aqueous battery, the heat resistance of the electrolytic solution is inferior, so even if the heat resistance of the gasket is improved, the heat resistance of the battery is not improved.

An insoluble and infusible polyacene film was synthesized by the production method described in Example 1 of JP-A-0. When the electric conductivity of the substance was measured at room temperature by a direct current 4-terminal method, 1
It was 0 −4 Ω −1 · cm −1 . According to elemental analysis, the atomic ratio of hydrogen atoms / carbon atoms was 0.27. The specific surface area by the BET method was an extremely large value of 2100 m 2 / g. Next, the polyacene film was pulverized with a ball mill for 3 hours to obtain a powder. To this powder, 5% by weight of polytetrafluoroethylene and 10% by weight of carbon black were added, mixed and pressure-molded to obtain a 0.2 mm thick polyacene sheet. Next, the separator made of the polyacene sheet and the borosilicate glass fiber non-woven fabric was punched into a disk shape, vacuum dried at 200 ° C. for 3 hours, and then placed in a jam pot and stored.

ｚ，１ｍＡ）の変化を表１に示す。A gasket formed by injection molding nylon 46, which is a polyamide resin of the present invention, was dried by vacuum drying at 100 ° C. for 3 hours and stored in a jam pot. Next, a conductive paste was applied to the bottom of the positive electrode can made of stainless steel, the above-mentioned polyacene sheet was placed on the bottom, pressure-bonded from above, and then dried at 100 ° C. for 30 minutes. Similarly, a conductive paste was applied to the inner bottom surface of a negative electrode can made of stainless steel, a polyacene sheet was placed thereon, pressure-bonded, and dried at 100 ° C. for 30 minutes. A propylene carbonate (1 mol / l) solution of tetraethylammonium borofluoride was injected as an electrolytic solution into the positive electrode thus obtained, and a separator was placed. In addition, after injecting a predetermined amount of the electrolytic solution into the negative electrode in the same manner, a diameter of 6.8 mm and a height of 0.9 as shown in FIG.
A 6 mm coin type (button type) organic electrolyte battery was assembled. All the above-mentioned assembling work was performed in the dehumidifying room. The organic electrolyte battery of the present invention produced as described above was subjected to reflow soldering such that the surface of the positive and negative electrode cans showed the temperature transition shown in FIG.
The change in z, 1 mA) is shown in Table 1.
