【考案の詳細な説明】 ＜産業上の利用分野＞ この考案は非水電解液電池に関し、特に、二酸化マンガ

れ用いて構成される非水電解液電池に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a non-aqueous electrolyte battery, and in particular, a non-aqueous electrolyte solution using manganese dioxide as a positive electrode active material and lithium as a negative electrode active material. It concerns batteries.
＜従来の技術＞ 二酸化マンガンを正極活物質とする非水電解液電池で
は、保存中において非水電解液が分解されることにより
発生する多量のガスにより電池が膨れたりあるいは内部
抵抗が上昇して、電池性能が劣化する欠点があることが
知られている。<Prior Art> In a non-aqueous electrolyte battery using manganese dioxide as a positive electrode active material, a large amount of gas generated by decomposition of the non-aqueous electrolyte during storage causes the battery to swell or the internal resistance to rise. It is known that there is a drawback that battery performance deteriorates.
上記の非水電解液の分解は、その詳細な原因は明らかで
はないが、二酸化マンガンの高電位部分，あるいは二酸
化マンガンの表面に存在する水酸基の酸触媒性により、
非水電解液中のプロピレンカーボネイトなどの有機溶媒
が分解されることによるものと考えられている。Although the detailed cause of the decomposition of the above non-aqueous electrolyte is not clear, due to the high-potential portion of manganese dioxide or the acid-catalytic property of the hydroxyl group present on the surface of manganese dioxide,
It is considered to be due to decomposition of an organic solvent such as propylene carbonate in the non-aqueous electrolyte.
このようなガス発生による性能劣化を防ぐため、従来技
術においては、特開昭58−68875号公報などに記載され

合もそれなりの効果を挙げている。In order to prevent the performance deterioration due to such gas generation, in the prior art, as described in JP-A-58-68875, a part of the battery capacity is discharged to adjust the voltage after the battery is assembled. , Thereby removing the high potential part of manganese dioxide, or, for example, Japanese Patent Publication No. 1-27550
As described in the publication, it is proposed that manganese dioxide is heat-treated at a high temperature with a reducing agent such as an alkaline earth metal hydroxide, and the reducing agent neutralizes the acid catalytic property of the surface of manganese dioxide. And, in each case, the effect is reasonable.

も提案されている。In addition to this, as shown in FIG. 3, for example, by mounting the lithium piece 20 on the surface of the positive electrode mixture 19 to assemble the battery,
During storage of the battery, the positive electrode mixture 19
There is also proposed a technique in which a part of the capacity of the above is discharged to remove the high potential part of manganese dioxide used as the positive electrode active material.
＜考案が解決しようとする課題＞ しかしながら、組立て後に電池容量の一部を放電させる
方法では、例えば工業的に大量に電池を生産する場合に
は生産設備の規模が大きくなることは避けられないし、
また必要とされる電圧調整をするのにかなりの時間がか
かることから工程は煩雑化する等の問題がある。特に容
量の大きな電池品種の場合には電圧調整に要する時間が
長くなり、この問題が顕著となる。<Problems to be solved by the invention> However, in the method of discharging a part of the battery capacity after assembling, for example, in the case of industrially producing a large number of batteries, it is inevitable that the scale of production equipment becomes large,
Moreover, since it takes a considerable time to adjust the required voltage, there is a problem that the process becomes complicated. Particularly in the case of a battery type having a large capacity, the time required for voltage adjustment becomes long, and this problem becomes remarkable.
また、還元剤を用いる場合も、上記のような熱処理を必
要とすることから、同様に生産設備の規模が大きくな
り、また工程が煩雑化するなどの問題がある。Further, even when a reducing agent is used, the heat treatment as described above is required, so that there is a problem that the scale of the production facility becomes large and the process becomes complicated.
一方、正極合剤表面にリチウム片を載置する方法の場
合、これらは単に接触した状態であることから、リチウ
ム片と正極合剤との電気的接触が不安定となりがちで、
このため正極合剤の放電が局所的に進み、上記高電位部
分の除去が均一に行えず、従って信頼性の高い放電処理
を行うことが困難で、放電後の電池性能のバラツキが大
きくなるという問題がある。On the other hand, in the case of the method of placing the lithium pieces on the surface of the positive electrode mixture, since these are simply in contact with each other, electrical contact between the lithium pieces and the positive electrode mixture tends to be unstable,
Therefore, the discharge of the positive electrode mixture locally progresses, the high-potential portion cannot be removed uniformly, and therefore it is difficult to perform highly reliable discharge treatment, and the dispersion of battery performance after discharge becomes large. There's a problem.
この考案は、上記の電圧調整や熱処理などを要すること
なしに簡便に二酸化マンガンの高電位部分の除去がで
き、またこの除去を確実に行え、従って電池組立て後に
おける電池の膨れや内部抵抗の上昇などをバラツキ少な
く抑えることが可能な、非水電解液電池を提供すること
を目的とする。This invention can easily remove the high-potential part of manganese dioxide without requiring the above-mentioned voltage adjustment and heat treatment, and can surely remove it, and therefore the swelling of the battery and the increase of the internal resistance after the battery is assembled. It is an object of the present invention to provide a non-aqueous electrolyte battery capable of suppressing such variations with little variation.
＜課題を解決するための手段＞ この考案の非水電解液電池は、リチウムを活物質とする

圧着したことを要旨とする。<Means for Solving the Problems> A non-aqueous electrolyte battery of the present invention is a power generation element including a negative electrode using lithium as an active material, a positive electrode mixture using manganese dioxide as an active material, and a non-aqueous electrolyte solution. In a non-aqueous electrolyte battery configured by hermetically housing in a battery case formed by combining a positive electrode can and a negative electrode terminal plate, the positive electrode can or a positive electrode current collector connected to the positive electrode can is provided with the positive electrode. The gist is that the lithium pieces are pressure-bonded in such a manner that a non-aqueous electrolyte holding space is interposed between the mixture and the mixture.
上記のリチウム片としては、正極合剤の容量（mAH）の
１〜５％の範囲の容量（mAH）のものを用いることが好

低下が顕著となる虞がある。As the lithium piece, it is preferable to use one having a capacity (mAH) in the range of 1 to 5% of the capacity (mAH) of the positive electrode mixture. If it is less than this range, the high potential part of manganese dioxide in the positive electrode mixture cannot be removed sufficiently, while even if a lithium piece having a capacity exceeding the above range is used, there is almost no effect of removing the high potential part. However, there is a possibility that the battery capacity may decrease remarkably due to a decrease in the storage space for the positive electrode mixture and the electrolytic solution.
また、本考案において、負極としてはリチウム単体の

Can be used. Further, as the non-aqueous electrolyte, it is possible to use a solution prepared by dissolving lithium perchlorate or the like as a solute in a solvent such as propylene carbonate, ethylene carbonate, dimethoxyethane and dioxolane, or a mixture of two or more thereof.
＜作用＞ 正極缶ないし正極集電体にリチウム片を圧着すること
で、電池組立て時よりリチウム片と正極合剤との放電が
開始され、従って前記のような電圧調整を要することな
く、電池を放置するだけで二酸化マンガンの高電位部分
の除去ができる。<Operation> By pressing the lithium piece on the positive electrode can or the positive electrode current collector, the discharge of the lithium piece and the positive electrode mixture is started from the time of battery assembly, and thus the battery can be assembled without the above voltage adjustment. The high potential part of manganese dioxide can be removed by leaving it alone.
また、リチウム片を正極缶ないし正極集電体に圧着した
ので、リチウム片と正極合剤との間の電気的接触が安定
し、この結果リチウム片と正極合剤との間の放電をバラ
ツキがきわめて少ない状態で行うことができる。In addition, since the lithium piece is pressure-bonded to the positive electrode can or the positive electrode current collector, the electrical contact between the lithium piece and the positive electrode mixture is stable, and as a result, the discharge between the lithium piece and the positive electrode mixture varies. It can be done in very few conditions.
