たりまたガス発生により電池が爆発することがある。Non-aqueous electrolyte batteries using lithium as the cathode active material are
Although a large discharge energy density can be obtained, since the cathode active material is highly reactive, trace amounts of water contained in materials used in batteries, such as electrolytes, anodes, separators, etc.
Alternatively, the discharge performance may deteriorate due to humidity during assembly, or the battery may explode due to gas generation.
そのため前記材料を使用するとき必ず脱水処理したり、

電にともなう端子電圧の降下が少い非水電解液電池を得
ることができた。The inventors of the present invention have conducted studies based on the opinion that using aluminum as a cathode active material instead of lithium is advantageous because water has less effect on battery performance. In non-aqueous electrolyte batteries, by adding a small amount of triethanolamine to the electrolyte, the discharge utilization rate of the cathode active material can be improved, resulting in non-aqueous electrolyte batteries with less terminal voltage drop during discharge. I was able to get it.

中における陰極活物質の安定性が良いため好適である。The electrolyte for this type of battery that uses aluminum as the cathode active material includes acetonitrile alone, or acetonitrile and ethylene carbonate,
Lithium or magnesium perchlorate dissolved in a solvent consisting of a mixture of propylene carbonate, butyrolactone, tetrahydrofuran, dimethoxyethane, etc., or a mixture of formamide and ethylene carbonate, propylene carbonate, butyrolactone, tetrahydrofuran, dimethoxyethane, etc. A solution of sodium or lithium borofluoride salt in a solvent, a solution of lithium chloride in a mixture of dimethylformamide, ethylene carbonate, propylene carbonate, or butyrolactone are used, and among these, an acetonitrile-based solvent is used. This is preferable because the cathode active material has good stability during storage.

質の放電利用率を次の表に示す。The amount of triethanolamine added is approximately 0.0% relative to the electrolyte.
A suitable amount is 5 to 3% by weight, but since increasing the amount beyond this amount has almost no effect on battery performance, the amount may be adjusted depending on the surface area of the cathode active material.
1 Using aluminum with an amalgamation rate of 1% by weight as the cathode active material, manganese dioxide as the anode active material, and a mixed solvent of acetonitrile and propylene carbonate in which 1.0 M/b lithium perchlorate was dissolved as the electrolyte, A button type battery without triethanolamine added to the electrolyte (comparative example) and a battery with approximately 1.5% by weight of triethanolamine added to the electrolyte (product of the present invention) each had a resistance of 500 Ω.
The following table shows the discharge duration and the discharge utilization rate of the cathode active material when continuous discharge was performed at 20° C. with a load resistor connected until the terminal voltage reached 0.9 V.
