うになってきた。In recent years, the consumption of electronic watches such as electronic wristwatches and calculators has been decreasing year by year, and the battery used as a power source is also required to have a longer life due to lower current consumption. Silver batteries were used for these batteries, but recently, non-aqueous electrolyte batteries that use lithium in the negative electrode, which has a higher energy density, have come into use.
非水電解液電池は銀電池より漏液しにぐいという利点を

に水分の除去のため真空で乾燥することが重要でおる。The results of the leakage test for the 2" L battery of the present invention obtained in this manner and the conventional battery are shown in Hikari 1. The test method was performed at a temperature of 60°C to 1
The sample was placed in a temperature cycle of 0° C. for 20 days to determine leakage. The number of tests was 100 each.Table 1 As is clear from Table 1, the battery of the present invention has excellent leakage resistance. This is because by applying a liquid sealant to the positive electrode can side, the adhesiveness between the positive electrode can and the insulating gasket is improved and liquid leakage is prevented. If the amount of liquid sealant applied is too large, it may flow into the center of the bottom of the positive electrode can and affect the total thickness of the battery.In experiments, the amount was 5 to 15 degrees (weight including toluene immediately after application, 1 degree after drying). 〇- or below) is good. If the dilution ratio of the liquid sealant is high, it will not be possible to apply it uniformly to the outer periphery of the positive electrode can when the amount of application is constant, and this will have a large effect on the leakage characteristics and the total thickness of the battery. When the dilution ratio is low, the effect of the liquid sealant becomes weak. In the experiment, the dilution ratio was 8~
15 times was appropriate. Furthermore, the effect is even greater when a liquid sealant is applied between the negative electrode can and the insulating gasket. In the drying process after applying the liquid sealant, it is especially important to dry it in a vacuum to remove moisture.
以上記載したように、正極缶に液体シール剤を塗布する
