Improved Silver-Zinc Batteries.
Abstract
In an effort to improve the cycle life, shelf life, and reliability of silver-zinc batteries, the performance capabilities of five different types were evaluated by the Power Sources Division of the Electronic Components Laboratory, US Army Electronics Command. Selecting a BB-622/U uncharged and dry type as most suitable for military applications, a number of improvements were made. The improved battery, designated BB-622A/U, has 28% fewer plates, 8.5% greater capacity, and additional separator layers for longer wet life with no increase in weight. Additional filling nozzles increased the number of cells that could be filled at one time, and soaking time was reduced from 72 to 48 hours. Further improvements involving the use of a monobloc casting rather than 4 cells taped together are contemplated.
