材からなる正極リングを嵌着して使用されている。(Prior Art) Organic solvent batteries have high energy density and excellent reliability, and are therefore used as power sources for many electronic devices. This battery uses a metal oxide, sulfide, or fluoride as the positive electrode, and a light metal such as lithium or sodium as the negative electrode, and these positive and negative electrodes are laminated with an electrolyte retaining material in between. Conventionally, a positive electrode ring made of a metal material such as stainless steel has been fitted and used.

など、幅広い性能が要求されるようになった。The use of such organic solvent batteries has been expanding rapidly in recent years, and they have heavy load characteristics when used as power sources for watches, cameras, radios, etc., and on the other hand, they are used as power sources for backing up memories built into OA equipment, home appliances, etc. When used as such, a wide range of performance is now required, including the need to maintain properties and stability over a long period of time.
このような要求に対応するため、電池を構成する正極合
剤、電解液組成あるいは電池構造等に関して多くの検討
がなされ、電池の特性レベルも相自白上してきた。In order to meet such demands, many studies have been made regarding the positive electrode mixture, electrolyte composition, battery structure, etc. that constitute the battery, and the level of battery characteristics has also been determined.
（発明が解決しようとする問題点）
しかしながら１時計、カメラ等に用いる有機溶媒電池に
あっては、なお要求が厳しく、重負荷特性を５〜１０年
間の長期に亘って維持することが求められている。(Problems to be solved by the invention) However, organic solvent batteries used in watches, cameras, etc. still have strict requirements, and are required to maintain heavy load characteristics for a long period of 5 to 10 years. ing.
ところが、この種の有機溶媒電池にあっては重負荷放電

に関与せず、従って電池としては作動電圧の異常低下や
重負荷特性の低下をもたらす等の問題を生じており、か
かる問題の発生は電池反応抵抗の高まる低温放電時に特
に顕著であった。However, in this type of organic solvent battery, the concentration of metal ions eluted from the negative electrode into the electrolyte increases during heavy load discharge, and the increase in polarization resistance of the positive electrode that absorbs these metal ions causes the metal ions in the electrolyte to increase. The concentration becomes excessive. At this time, as mentioned above, conventionally, metal materials with good electronic conductivity such as stainless steel are used for the positive electrode ring, so excess metal ions combine with electrons on the positive electrode ring and precipitate as metal. . For this reason, metal ions do not participate in the original discharge reaction, causing problems such as an abnormal drop in operating voltage and deterioration of heavy load characteristics for batteries. This was especially noticeable during low-temperature discharge.
本発明は、かかる問題点を解決することにより、低温に
おいても良好な重負荷特性を維持しうる有機溶媒電池を
提供することを目的とする。An object of the present invention is to provide an organic solvent battery that can maintain good heavy load characteristics even at low temperatures by solving such problems.

。[Structure of the Invention] (Means for Solving the Problems) The organic solvent battery of the present invention has a positive electrode having a positive electrode ring fitted to the peripheral edge thereof, and a negative electrode made of a light metal, which are laminated with an electrolyte holding material interposed therebetween. An organic solvent is used as the electrolytic solution, and the positive electrode ring is made of a material having an electrical resistance of 1/10 to 10 times that of the positive electrode mixture.

しまうので好ましくない、より好ましくは、正極リング
は正極合剤のｌ／４〜４倍の電気抵抗、最も好ましくは
正極合剤と同一の電気抵抗を有していることである。Here, if the electrical resistance of the positive electrode ring is lower than 1/1O of the electrical resistance of the positive electrode mixture, metal ions will precipitate as metal on the positive electrode ring during heavy load discharge as described above, resulting in an abnormal decrease in the operating voltage. On the other hand, if the electrical resistance of the positive electrode ring is higher than 10 times the electrical resistance of the positive electrode mixture, the part of the positive electrode mixture where the positive electrode ring is fitted will be shielded, and its As a result, the effective reaction area of the positive electrode that participates in the electrode reaction decreases, which is undesirable because the discharge characteristics deteriorate. More preferably, the positive electrode ring has an electrical resistance of l/4 to 4 times that of the positive electrode mixture, and most preferably has the same electrical resistance as the positive electrode mixture.

持することができる。(Function) If the organic solvent battery of the present invention is used, even if the polarization resistance of the positive electrode increases during single-load discharge, precipitation of metal ions on the positive electrode ring can be prevented, and the effective reaction area of the positive electrode can be reduced. Therefore, good heavy load characteristics can be maintained even at low temperatures.
