SILVER-ZINC ELECTRODES AND SEPARATOR RESEARCH

Abstract

Polyethylene glycols in a molecular weight range of 1000 give comparable cycle life with tridecyloxy poly(ethyleneoxy)ethanols. It is surmised that the polyethyleneoxide structure is active in promoting cycle life. The addition of .25% Pb in ZnO tends to reduce agglomeration of the formed zinc and to prolong cycle life. The limit of .010% Fe in ZnO is tolerable for satisfactory cycle life. The use of CaO in the negative material to produce insoluble sites for zincate stoppage is not satisfactory. Some evidence of pore sizes of various separator membranes have been found through electron microscope studies. Increasing the stoichiometric ratio of formed zinc is not practical in terms of redesigning the present cell because of increased volume with a small increase in cycle life. The 90 Mrad precrosslinked polyethylene base, radiation grafted methacrylic acid membrane is suitable for use as a separator in secondary silver-zinc batteries.
