本発明は外装部材の封止の改良を図つた可撓性薄型電池
の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a flexible thin battery with improved sealing of an exterior member.

。そこで自在な折り曲げ、湾曲、変形に耐え、より薄く
面積の広い可撓性薄型電池が検討されている。Conventionally, batteries in which power generating elements are encapsulated in a polymer film are known as paper batteries, sheet batteries, etc., but it has not been possible to maintain stable battery performance even after repeated bending and deformation. Therefore, careful handling was required. Therefore, flexible thin batteries that can withstand flexible bending, curving, and deformation and are thinner and have a wider area are being considered.

加わるが、全ての条件をほぼ満足するものは極めて少な
く、しかもそれらは難接着性であるものがほとんどであ
り、封止は容易なものではなかつた。However, among such flexible thin batteries, many chemical batteries such as manganese batteries, mercury batteries, silver oxide batteries, and lithium batteries use various inorganic electrolytes or organic solvents such as acidic, neutral, and alkaline. Although the power generating element contains an organic electrolyte in which salt is dissolved in the flexible exterior member, minute capillaries and gaps are likely to occur after adhesion or welding during the sealing process of the flexible exterior member, and it is difficult to completely seal it. Even if it is sealed, as it is repeatedly bent and curved, capillary tubes and gaps will form, causing leakage and internal shortening.
This was a step forward in terms of reliability as a thin, flexible battery. In addition, in physical batteries such as solar cells and photovoltaic cells that use amorphous silicon, cadmium sulfide, selenium, etc. as power generating elements, flexible exterior members are superior in light transmittance, light resistance, and heat resistance. Although these are added as conditions for selection, there are very few that almost satisfy all of the conditions, and most of them are difficult to adhere to, making sealing difficult.
封止強度・密閉性に関する前記問題点は、屋外環境での
使用を主とする該電池にとつて本質的に要望されている
耐湿性、耐熱性等の耐環境性が充分でなく、実用に適す
る品質の向上が希求されていた。The problem with sealing strength and airtightness is that the environmental resistance such as moisture resistance and heat resistance, which are essentially required for batteries mainly used in outdoor environments, is not sufficient, making them difficult to put into practical use. There was a desire for improved quality.
本発明はかかる実情に鑑みなされたもので、発電要素を

を得ることにある。The present invention has been made in view of the above circumstances, and includes applying ultraviolet irradiation treatment to the inward surface of the sealing portion of a flexible exterior member enclosing a power generation element in advance, and then sealing with adhesive or heating. The object of the present invention is to obtain a flexible thin battery having perfect sealing and adhesive strength that does not cause cracks or gaps even when bent or bent.
以下、本発明を実施例に基ずいて詳細に説明する。Hereinafter, the present invention will be explained in detail based on examples.
