Abstract
The problem of this thesis is to study the plating prohibitive properties of the various materials commonly used in the manufacturing of separators, and to indicate which material would be most serviceable and feasible in a separator. At one time positives and negatives were kept not more than 0.25 inches apart, with the idea of reducing the intervening layers of electrolyte, and, therefore, the internal resistance of the cell, as much as possible. It was, however, found that the output could actually be increased by putting the plates at greater distances, the fact being that the larger bulk of solution thus brought into close proximity to the active material was better able to maintain the strength of acid within its pores; and the higher potential difference consequent upon the diminishing of polarization more than compensated for a slight loss in other directions. It has been found that stout glass tubes make the best distance pieces. Electrolytes have some impurities which are difficult to remove, and sometimes they cannot be removed. These impurities tend to plate out and this causes an appreciable decrease in the performance of the battery. Separators that prevent plating as much as possible are therefore necessary.
