イ）産業上の利用分野
本発明は非水電解液電池に係り、特に正極の改良に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION A) Field of Industrial Application The present invention relates to non-aqueous electrolyte batteries, and particularly relates to improvements in positive electrodes.
（切 従来の技術
この種電池の正極は、金属の酸化物、硫化物或いは、ハ
ロゲン化物などの活物質に導電剤及び結着剤を加えた混
合物を熱処理して作成されている。(BACKGROUND ART) The positive electrode of this type of battery is made by heat-treating a mixture of an active material such as a metal oxide, sulfide, or halide, to which a conductive agent and a binder are added.
ここで結着剤としては耐電解液性は勿論のこと、水分除
去工程における加熱処理に耐え得るものであることが必
要であり、この観点より例えば特公昭４８−２５５６８
号公報に開示されているフッ素樹脂が一般的に用いられ
ている。Here, the binder must not only have electrolytic solution resistance but also be able to withstand heat treatment in the water removal process.
The fluororesin disclosed in the above publication is generally used.
しかしながら、フッ素樹脂を用いる場合には正極の機械

活物質の放電利用率の低下を招き、又単位体積当りの活
物質Ｉｋが減少し、電池の放電容量の低下を来たすとい
う欠点がある。However, when using fluororesin, in order to maintain the mechanical strength of the positive electrode to a practical level, it must be used in a large amount, such as 10 to 20% by weight, based on the positive electrode, and a large amount of binding The use of such agents causes a decrease in the liquid absorption of the positive electrode and a decrease in the discharge utilization rate of the active material, and also has the disadvantage that the active material Ik per unit volume decreases, resulting in a decrease in the discharge capacity of the battery.
このような欠点を改善するために、結着剤の添加かを削
減する代わりに正極の外周をステンレス缶で補強したり

強することが提案されているが、これらの方法では極板
成型時の工数アップ、発電要素以外の部品（内借など）
を電池内に組み入れることによる電池内有効体積の減少
を招くことになる。In order to improve such drawbacks, instead of reducing the amount of binder added, the outer periphery of the positive electrode is reinforced with a stainless steel can, or Japanese Patent Application Laid-Open No. 59-214159,
As disclosed in Japanese Patent No. 230257, it has been proposed to strengthen the positive electrode by placing a porous conductor such as gold on one side or the inner surface of the positive electrode, but these methods increase the number of man-hours required for molding the electrode plate. , parts other than power generation elements (rented etc.)
Incorporating this into the battery results in a decrease in the effective volume within the battery.
又、特開昭５９−１８９５５９号公報においてはフッ素
樹脂結着剤とポリビニールアルコールなどの粘性剤とを
併用することが提案されているが、この方法では正極合
剤の混合工程や正極の加熱処理工程が複雑で工数が多（

るという欠点がある。更に、フッ素樹脂結着剤を用いた
正極合剤は流動性に乏しく、そのため正極合剤を秤量す
る際の精度が悪く、極板製造時における作業性、均一性
に難点がある。Furthermore, in JP-A-59-189559, it is proposed to use a fluororesin binder and a viscous agent such as polyvinyl alcohol in combination, but this method does not require the mixing process of the positive electrode mixture or the heating of the positive electrode. The processing process is complicated and requires a lot of man-hours (
Moreover, although the strength of the obtained electrode plate is improved compared to the electrode plate using only fluororesin, it cannot be said to be sufficient, especially when the thickness is 2.
When an extremely thin electrode plate, such as an electrode plate used in a battery of m+ or less, is produced by this method, there is a drawback that the electrode plate may be cracked or missing during assembly. Furthermore, a positive electrode mixture using a fluororesin binder has poor fluidity, resulting in poor accuracy when weighing the positive electrode mixture, and problems with workability and uniformity during electrode plate manufacture.
そこでフッ素樹脂に代わるものも種々提案されている。Therefore, various alternatives to fluororesins have been proposed.

(Japanese Unexamined Patent Publication No. 58-147965) or sodium polyacrylic acid, both of them have problems in battery characteristics or manufacturing, and the strength of the electrode plate is insufficient even if it is extremely thin.
ｅｊ 発明が解決しようとする問題点前述せる従来の
結着剤による電池特性の低下、作業上の問題などを解決
しようとするものである。ej Problems to be Solved by the Invention The invention attempts to solve the aforementioned problems such as deterioration of battery characteristics caused by conventional binders and operational problems.
に） 問題点を解決するための手段
本発明は正極の結着剤としてシリコン・アクリル共重合
樹脂を用いることを特徴とする。B) Means for Solving the Problems The present invention is characterized in that a silicone-acrylic copolymer resin is used as a binder for the positive electrode.
シリコン・アクリル共重合樹脂の添加量としては正極に
対して０．５〜３．０重量％の範囲が好ましい。The amount of silicone-acrylic copolymer resin added is preferably in the range of 0.5 to 3.0% by weight based on the positive electrode.
（ホ）作用
本発明による結着剤はシリコンを含有し分解温度が高い
ので３００℃以上の高温においても結着剤の造膜作用は
進行し分解することがない。(E) Function Since the binder according to the present invention contains silicon and has a high decomposition temperature, the film-forming action of the binder proceeds even at high temperatures of 300° C. or higher, and the binder does not decompose.
そのため正極の高温熱処理が可能となり、正極中の水分
を充分に除去でき、残存水分による電池特性の劣化を抑
制しうる。Therefore, high-temperature heat treatment of the positive electrode is possible, moisture in the positive electrode can be sufficiently removed, and deterioration of battery characteristics due to residual moisture can be suppressed.
又、本発明による結着剤は単独で使用しても極薄形極板
において充分な機械的強度が得られるため、ポリビニル
アルコールなどの粘−１，主剤が不要となり、その結果
粘性剤除去のための熱処理工程が削除でき作業性が向上
する。In addition, even when the binder of the present invention is used alone, sufficient mechanical strength can be obtained in ultra-thin electrode plates, so a viscous agent such as polyvinyl alcohol is not required, and as a result, it is easy to remove the viscous agent. The heat treatment process for this process can be eliminated, improving work efficiency.
更に本発明による結着剤は高温中においても熱的に安定
な膜を形成し、非水電解液電池で大きな問題となる結着
剤の分解溶出を因とする電池性能の劣化が抑えられる。Furthermore, the binder according to the present invention forms a thermally stable film even at high temperatures, and deterioration of battery performance due to decomposition and elution of the binder, which is a major problem in non-aqueous electrolyte batteries, can be suppressed.

5% of pure water was added to this mixture, kneaded, and dried at 90° C. for about 10 hours. After drying, the product was pulverized and subjected to 32 mesh passes, and then pressure molded.
A positive electrode was prepared by heat treatment at ℃ for 120 minutes. The dimensions of the positive electrode are 16.3% in diameter and 0.57% in thickness.

活物質量の減少及び結着剤の造膜作用により電極中への
電解液の浸透性が低下するためと考えられる。As is clear from FIG. 1, the electrode plate strength exceeds 100y when the silicone-acrylic copolymer resin additive 7+tllu is 0.5% by weight or more. By the way, Japanese Patent Publication No. 5
In the conventional positive electrode according to Publication No. 9-189559, it is about 80j, whereas! 311ffl shows the relationship between the amount of silicone-acrylic copolymer resin added and the battery discharge time. The discharge conditions are temperature 23°C, load 12, Ω, and discharge end voltage 'Lo.
As is clear from Figure 3, when the amount of silicone-acrylic copolymer resin added is 3.0% by weight or more, the discharge time becomes shorter (the tendency for it to become shorter becomes greater). This is thought to be because the permeability of the electrolyte into the electrode decreases due to the decrease in the amount of active material and the film-forming action of the binder.
