効率よく行なわれたとこと意味していると考えられる。(Left below) As is clear from Table 2, battery expansion depends on the voltage conditions of the withstand voltage test, but the withstand voltage test generally required for this type of secondary battery is 1.75 to 1. 907 for 200
When judging on the basis of 0 hours, battery person and B are 200
Expansion of the battery was observed within 0 hours. On the other hand, no expansion was observed in batteries 0.1), R, and F in which the amount of cadmium added was 6% by weight or more. This is considered to mean that oxygen gas was efficiently absorbed when the amount of cadmium powder added was 6 weight factors or more.
