APPLIED RESEARCH INVESTIGATION OF SEALED SILVERZINC BATTERIES.
Abstract
Cycle life studies were made on groups of cells in which the ratio of ZnO to silver was varied from 0.75:1 to 4:1. Maximum life was obtained at the 2:1 ratio. Electrolyte quantity tests indicate that both initial capacity and cycle life are improved if a high electrolyte level is provided. This is discussed in terms of sealed-cell operation. Dynel-wrapped negatives have shown decreased cycle life so far. Additional testing is under way. Cells containing NaOH electrolytes are still under test. Utilization of the maximum LiOH concentration as the electrolyte sharply reduced both capacity and cycle life. Neither CdO additions to the negative active material nor provision for double grids in the negative plate construction showed advantages in initial capacity or cycle life. A detailed theoretical study concerning the possibility of utilization of neutral salt electrolytes in silver-zinc cells is reported. (Author)
