改善されることを見出した。 The inventors of the present invention have conducted various experiments in view of the above-mentioned problems, and have found that the use of thiophene as the organic solvent of the electrolytic solution improves the battery characteristics in high-rate discharge and low-temperature discharge.
本発明は上記実施例に基づきなされたものであ
り、以下その実施例について詳述する。 The present invention has been made based on the above embodiments, and the embodiments will be described in detail below.
電解液としてチオフエンに１モル／過塩素酸
リチウムを溶解したものを用いた。 The electrolytic solution used was one in which 1 mole/lithium perchlorate was dissolved in thiophene.
正極は二酸化マンガン活物質85重量％に導電剤

Electrolyte battery A was created.

ことがわかる。 Figures 1 and 2 show the high rate discharge characteristics (room temperature, 560Ω constant resistance discharge) and low temperature discharge characteristics (-
20° C., 5.6KΩ constant resistance discharge), and it can be seen from these characteristic diagrams that the battery of the present invention dramatically improves both high rate discharge characteristics and low temperature discharge characteristics.
この理由を考察するに、各比較電池に用いた有
機溶媒、即ちプロピレンカーボネートはその粘度

トキシエタンは、溶質の溶解度が小であるためい
づれも電解液の電導度が低い。 Considering the reason for this, we found that the organic solvent used in each comparative battery, namely propylene carbonate, has an extremely high viscosity of 2.53 cps, and that 1,2 dimethoxyethane has a low solubility of the solute. Electrolyte has low conductivity.
これに対してチオフエンはその粘度が0.621cps
と小であり且つ溶質の溶解度も大であるため電解
液の電導度が高いことに依るものであると考えら
れる。 On the other hand, thiophene has a viscosity of 0.621 cps.
This is thought to be due to the high conductivity of the electrolytic solution, since the solubility of the solute is small and the solubility of the solute is high.
尚、実施例ではチオフエン単独の場合について
例示したが、他の有機溶媒と組合せ混合溶媒の形
体で用いることもできる。 In the examples, thiophene was used alone, but it can also be used in the form of a mixed solvent in combination with other organic solvents.
上述した如く、本発明は有機電解液電池に関す

り、その工業的価値は極めて大である As mentioned above, the present invention relates to an organic electrolyte battery, and the use of thiophene as a solvent in an electrolyte consisting of at least one solvent and at least one solute improves the high rate discharge characteristics of this type of battery. It can improve low-temperature discharge characteristics, and its industrial value is extremely large.
