Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は平板形電池の改良に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to improvements in flat batteries.

性を向上するものである。The present invention provides a flat plate battery with a protruding part on both positive and negative terminal plates for connection to an electric circuit, and the entire surface of the battery except for a part of the protruding part is made of electrically insulating material such as synthetic resin. The reliability of sealing is improved by applying a coating.

より成り、その面が露出されたままにされている。Conventionally manufactured flat plate batteries have a positive electrode active material held on a positive terminal plate and a negative electrode active material held on a negative electrode terminal plate, separated by a separator to prevent contact between the two materials, and electrolyte solution throughout the inside of the battery. It has been manufactured by bonding and sealing the peripheral edges of terminal plates of both positive and negative electrodes using an electrically insulating material. The positive terminal plate and the negative terminal plate are made of stainless steel or nickel thin plate or foil, and their surfaces are left exposed.
平板形電池は、正極端子板と負極端子板の間隔が狭く短
絡をおこしやすい。又、周縁部分は金属と封止材の接合
面が外気に対し露出しており、電池の封止に関する信頼
性は、金属と封止材の接着の程度に依存していた。この
接着は、概して水分湿度の影響を受けることが認められ
ている。従って従来の平板形電池は、封止の信頼性の向
上が必要とされていた。In flat plate batteries, the distance between the positive terminal plate and the negative terminal plate is narrow and short circuits are likely to occur. Further, in the peripheral portion, the bonding surface between the metal and the sealing material is exposed to the outside air, and the reliability of sealing the battery depends on the degree of adhesion between the metal and the sealing material. It is recognized that this adhesion is generally influenced by moisture humidity. Therefore, it has been necessary to improve the sealing reliability of conventional flat batteries.
これらの課題の解決のため、本発明では電池が封止され
ている全周縁部分を含む端子板全体を電気絶縁性の材料
を用いて、被覆コーティングする。In order to solve these problems, in the present invention, the entire terminal board including the entire periphery where the battery is sealed is coated with an electrically insulating material.

ましい。Further, for connection with an electric circuit, a protrusion is provided on the terminal board, and only a portion, which is mainly the tip of the protrusion, is not covered with the above-mentioned coating. The material to be coated is desirably a material that has a certain degree of adhesion, welding, adhesion, or other bonding strength to the metal surface and is difficult to transmit moisture.

絶縁性を有する被覆で覆われているため、短絡の危険性

又、周縁の封止部分は、外側を被覆材で覆われ、外気に
直接触れることがなくなるため、封止部分からの水分の
浸入がなくなり、封止の信頼性が向上する。In addition, since the outer side of the sealed portion at the periphery is covered with a covering material and is not exposed to the outside air directly, there is no infiltration of moisture from the sealed portion, and the reliability of the sealing is improved.

lfc) and +dl are a plan view, a front view, an enlarged sectional view of part A, and an enlarged sectional view of part B, respectively. A positive electrode active material 4, a separator 5, and a negative electrode active material 6 are arranged together with an electrolyte between a positive electrode terminal plate 1 and a negative electrode terminal plate 2, and the peripheral edge of the terminal plate is adhesively sealed with a synthetic resin sealant 3. did. The terminal plate was provided with a protrusion 1a on the positive terminal plate and a protrusion 2a on the negative terminal plate. A coating 7 of an insulating material was applied to the entire protrusion, leaving only parts lb and 2b. In the present invention, all of the protrusions lb and 2b of the terminal board are insulative, and can be handled with a metal pin or the like without any problem, making it easier to handle than conventional products. Furthermore, even if a large number of them are stacked directly without putting them in a package, no electrical short circuit will occur, improving safety. The sealed portion of the conventional product peeled off in a short time when immersed in water, but the product of the present invention did not peel off even when immersed in water, and was found to be resistant to environmental conditions.
なお、従来品は第１図において、被覆コーティング７か

電気的短絡が防げ水分にも強いという効果がある。As explained above, by coating the entire battery with an electrically insulating material except for a part of the protrusion of the terminal plate of a flat plate battery, handling becomes easy and electrical short circuits can be prevented. It also has the effect of being resistant to moisture.
