A program for the development of a stable long-life zinc electrode was initiated. A cell parameter study was undertaken to investigate the relationship between binder, electrode area ratio, silver to zinc ratio, and electrode height-to-width ratio. A statistical design was developed and cells constructed based on this design. Techniques of preparing wet-proofed zinc oxide were studied. Two basic methods were evaluated and a successful batch technique was developed. Studies on methods of using the zinc electrode in a sealed cell system were initiated. The study was limited to an evaluation of third electrodes in silver-zinc oxide cells. Three types of platinum and carbon third electrodes are being studied. The data, to date, indicate that difficulties will be encountered when platinum electrodes are used.
