［発明の技術的背景とその問題点］
最近、電子機器の小形化、薄膜化が進展するに伴って、

が大きな技術的課題となってきている。[Technical background of the invention and its problems] Recently, as electronic devices have become smaller and thinner,
There is also a strong demand for smaller and thinner batteries for these power sources. In particular, so-called sheet batteries and paper batteries, which are suitable for card-type electronic devices such as memory cards and IC cards, have been put into practical use. In order to make these batteries thinner, the method of sealing the batteries has become a major technical issue.
これらの薄形゛電池は、集電体を兼ねる正負両極の平板
状外装板の周縁部を、熱接着性樹脂で密封する構造が提
案されている。For these thin batteries, a structure has been proposed in which the periphery of a flat exterior plate with both positive and negative electrodes, which also serves as a current collector, is sealed with a thermoadhesive resin.
この熱接着性樹脂としては１次のような特性が要求され

い特性が必要である。This thermoadhesive resin is required to have the following first-order characteristics. In other words, as the thickness of the positive and negative electrodes becomes smaller,
There is a need for a sealing material that maintains sufficient insulation between the two electrodes, has good adhesion, does not leak electrolyte, and has excellent long-term storage stability. Furthermore, from the viewpoint of high energy density, a so-called non-aqueous electrolyte lithium battery type thin-film battery has been developed, using lithium as the negative electrode active material and a non-aqueous electrolyte containing an inorganic salt dissolved in an organic solvent as the electrolyte. It is actively practiced. In this case, the sealing material must also have characteristics that make it difficult to absorb moisture that easily reacts with lithium from the outside, and that it is chemically stable to organic electrolytes and does not cause swelling.

どの変性体を用いることを提案している。These methods utilize the fact that polyolefin resin is nonpolar and therefore has excellent chemical and electrical properties. However, polyolefin resins have poor adhesive properties, and therefore, in the above-mentioned conventional technology, it is difficult to use modified products such as copolymers of ethylene and vinyl acetate, ionomer resins, or polyolefin resins grafted with unsaturated carboxylic acids. is suggesting.

求められている。However, these modified products cannot necessarily be said to have sufficient adhesive properties to satisfy the above-mentioned required characteristics as a sealing material due to low heat resistance, poor chemical resistance, etc. Batteries using this as a sealing material have problems with long-term reliability, and there is a need for a sealing material with even better adhesive properties.

性質の改良を目的とした改良研究などが行なわれている
。Polyamide resin is effective as an adhesive for bonding the surfaces of various materials such as metal materials such as copper plates and aluminum plates, and plastics, so it has traditionally been used for such purposes. Improvement research is being carried out with the aim of improving various properties of these materials.

よるポリアミド樹脂の改質などを利用する接着特性の改
良が以前から提案されている。In other words, when a polyamide homopolymer is used alone as a polyamide resin, it cannot be said to have sufficient adhesive strength, so in order to increase the adhesive strength, various reactive monomers are added during the production of the polyamide resin. Improvements in adhesive properties have been proposed for some time, such as by modifying polyamide resins by using epoxy resins, using epoxy-based primers in combination, or modifying polyamide resins by adding a third component to form a composition.

(Japanese Unexamined Patent Publication No. 51-67833), an adhesive composition containing a polyamide resin and a specific organosilicon compound (Japanese Unexamined Patent Publication No. 1983)

トメルト接着剤としての性能の向上はある程度見られる
が、上記の組成物封口材としての要求特性を満足させる
ほど充分な接着性を有していることは言えない。Although the performance of the polyamide resin as a hot melt adhesive is improved to some extent by the addition of these additive components, the adhesiveness of the polyamide resin must be sufficient to satisfy the required properties as a composition sealing material as described above. I can't say that.
