る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an organic electrolyte battery using lithium as a negative electrode active material and iron sulfide and cupric oxide as positive electrode active materials, and particularly improves the closed circuit voltage at the end of discharge. The purpose is to measure.

してその発展が期待されている。 Organic electrolyte batteries that use iron sulfide or cupric oxide as positive electrode active materials have a larger electrical capacity per unit volume and have a higher discharge capacity than organic electrolyte batteries that use manganese dioxide or carbon fluoride as positive electrode active materials. It has a voltage of approximately 1.5V and is compatible with commercially available Lecrancier batteries and silver oxide batteries, and its development as a high energy density battery with a large electrical capacity is expected.

放電反応が２段になり放電電圧が平担性に欠ける
などの欠点があるため、前記のような長所は認め
ながらも、充分に活用されるまでにはいたらなか
つた。 However, when iron sulfide is used as a positive electrode active material, there are problems such as discharge products accumulating on the positive electrode, causing the positive electrode to swell and increase in volume, causing the battery to swell and damaging equipment using the battery. There is,
In addition, when cupric oxide is used as a positive electrode active material, there are disadvantages such as a two-stage discharge reaction and a lack of flatness of the discharge voltage, so although cupric oxide is recognized as having the above advantages, it is not fully utilized. I didn't get there until now.

たつた。 Therefore, the present inventors have conducted extensive research in order to obtain a battery that takes advantage of the strengths of iron sulfide and cupric oxide while eliminating their drawbacks, and has mixed these iron sulfides and cupric oxide. By using these as positive electrode active materials, it is possible to obtain an organic electrolyte battery with a flat discharge voltage, less battery swelling due to discharge, and a larger discharge capacity than when each of these is used alone. I discovered that
A patent application has already been filed for this, but as a result of further research, a positive electrode mixture containing iron sulfide and cupric oxide as positive electrode active materials was prepared and pressure-molded, and iron sulfide and cupric oxide were used as positive electrode active materials. The positive electrode has a two-layer structure of a layer containing copper as the positive electrode active material and a layer using cupric oxide as the positive electrode active material, and the layer using cupric oxide as the positive electrode active material is on the separator side, and iron sulfide is used as the positive electrode active material. When a layer serving as the positive electrode active material is placed on the bottom side of the positive electrode can, it has all the characteristics of using a mixture of iron sulfide and cupric oxide as the positive electrode active material, while maintaining a closed circuit at the end of discharge. It was discovered that the voltage was even higher than when the above mixture was used, and the present invention was completed.

閉路電圧が高くなる理由は、現在のところ必ずし

対向する側に配した酸化第二銅が正極缶缶底側の
鉄の硫化物より優先的に放電して、電導性の良好
な金属銅が生成するので界面の電導性が改良され
て放電反応がスムーズに進行するようになるため
であると考えられる。 The positive electrode has a two-layer structure of a layer using iron sulfide as the positive electrode active material and a layer using cupric oxide as the positive electrode active material,
At present, the reason why the closed circuit voltage at the end of discharge is higher by disposing a layer containing cupric oxide as the positive electrode active material than when a mixture thereof is used as the positive electrode active material is not necessarily explained. Although it is not clear, the cupric oxide placed on the separator side, that is, the side facing the negative electrode, discharges preferentially over the iron sulfide on the bottom side of the positive electrode can, producing metallic copper with good conductivity. This is thought to be because the electrical conductivity of the interface is improved and the discharge reaction proceeds smoothly.
