摘要： PROBLEM TO BE SOLVED: To eliminate the difference in degradation due to mismatching of plates and the difference in heat radiation so as to extend the life by making the capacity of each negative plate except those at ends greater than that of the adjacent positive plate. SOLUTION: If there is capacity mismatching such that the capacity of a negative plate is smaller than that of the adjacent positive plate, absorption of oxygen gas during overcharging is worse accordingly, leading to a shorter life. Therefore, since the negative plates located at the ends or plates are such that their outer surfaces not opposed to the positive plates do not participate in oxygen gas absorption, for the negative plate with an electrode mix applied to both sides of its core the mix is applied only to the part opposite to the positive plate, thereby making its capacity greater than half the capacity of the adjacent positive plate. Also, the positive and negative plates at the center of the group of plates have a greater capacity than those at the ends of the group of plates. In the case of a group of plates in which a number of plates are stacked, heat radiation at the center of the group is bad and degradation is likely to progress. Therefore by adopting the above constitution, early degradation at the center of the group is restrained to equalize the degrees of degradation of the plates throughout the group.
