Hydroxide-Limited Silver-Zinc Cells

摘要

Silver-zinc cells under certain circumstances can be limited in capacity by the amount of hydroxide ion added during cell activation. This report examines the reasons for this limiting condition and suggests techniques to determine whether cells are limited by their hydroxide content. In addition, the report found that the projected cell capacities as a function of wet-stand duration followed the same capacity trend line as a group of cells that were affected by hydroxide-limitation problems that resulted in low ampere capacities during cell discharge.
