Method of fabricating a titanium and silver complex-impregnated cellulosic separator for electrochemical cells involves impregnating a sheet of regenerated cellulose at elevated temperature in an aqueous environment simultaneously with two different selected reagents, one containing silver and the other titanium. By the impregnation, silver and titanium are thus separately but simultaneously introduced into the cellulose to form a silver-titanium complex therewith, improving the oxidation resistance of the cellulose when the cellulose is used as a separator in an electrochemical cell. The sheet also exhibits improved resistance to the penetration of silver when incorporated into an electrochemical cell having silver as one of the electrodes, zinc as the other electrode and an alkali hydroxide as the electrolyte. |
