Abstract:

A study was made of the Ag io migration within the cell during cycling. Di tribution of Ag in the various layers of separator was determined asA FUNCTION OF THE NUMBER OF CYCLES. A comprehensive study of the Zn electrode was partially completed. The effect of current density and certain addition materials was determined in terms of Zn particle size increase during cycling. Methods of controlling Zn penetration of the separator material were established. Other investigations included gas producing reactions at both the negative and positive plates, pressure control, effect of alloying elements on the voltage characteristics of the positive plate, production of a molded terminal seal resistant to KOH leakage. A sealed cell was constructed and cycled over a 20 capacity range for 590 cycles. The pressure change was from a 10 p i vacuum to a 9 psi positive pressure.
