Description of the Related Art Polypropylene has usually been used for the sealing parts of conventional coin-type lithium batteries and coin-type electric double layer capacitors. After applying sealant to the sealing part of the upper case and fitting it into the packing, all the electrodes are attached to the upper and lower cases, and the electrolyte and separator are filled, and the upper case integrated with the packing is mated. It was customary to fully seal the end opening of the T-case to obtain a sealed part.

る。Problems to be Solved by the Invention Coin-type lithium batteries and capacitors are often used as backup power sources for computer memory. Especially when used for control purposes as automobile parts, etc.
Even if conventional products are reliable in the operating range of 10°C to 60°C, automotive parts and the like require temperatures of about 0°C to 85°C, and there are no longer enough products with sufficient leakage resistance. This problem is mainly caused by the fact that the polypropylene used for packing suddenly increases its elastic modulus and becomes brittle at low temperatures (-40°C), and that stress relaxation becomes significant when the temperature exceeds 70°C. This is probably because it is not suitable.

介在させたことを特徴とするコイン型封口部品である。In order to improve impact strength at low temperatures (-40°C), heat resistance at high temperatures (86°C), and stabilize thermal deformation, the inventors have developed the following methods: This led to the invention of coin-shaped sealing parts. That is, the coin-shaped sealing part is characterized in that a packing made of a polymer blend of polyamide and at least modified polypropylene is interposed in the sealing part of the sealing part.

る。More specifically, a coin-shaped sealing part is suitable when the sealing part of the sealing part is configured with a sealant and the packing, and a coin-shaped sealing part is suitable when modified polypropylene is modified with an acid anhydride such as maleic anhydride. It is a mold sealing part. Further, the polyamide may be 6-9 or 66-9.
Nylon is the optimal coin-shaped sealing part. or,
The coin-shaped sealing part is optimal when the sealing agent that further improves the sealing property is a fatty acid polyamide having an amine value of 50 or less, epoxy adduct amine, asphalt pitch, silicone, thiol resin, or a mixed composition thereof.

られる。Polyamide, which has a single function, has a high water absorption capacity and
For example, the resulting insulation resistance is less than 1Q14Ω/cTn, which is insufficient for packing between electrodes.Additionally, by blending modified polypropylene with a polymer, the insulation resistance becomes more than 1015Ω/α, and water absorption is also improved. The reduced zero-modified polypropylene is 4 Q wt
% or less, 18. The results show that the heat distortion temperature of H/errt is 100° C. or higher, and the heat resistance is also suitable for practical use. Further, it is preferable to use a sealant, and polyamide or silicone conductive sealants, which have a high heat deformation temperature due to their molecular structure, exhibited the most preferable leakage resistance. This is thought to be because the thermal shock leakage test is conducted in a cycle of 140°C to 85°C, so it follows the expansion and contraction of each component.
