THE USE OF POLYMERIC COMPLEXES TO MODIFY CATHODES OF AIR-ZINC CELLS WITH SALT AND ALKALINE ELECTROLYTES

The electrocatalytic activity of cathodes of air-zinc cells with alkal ine and salt electrolytes, whose active masses contain polymeric macro heterocyclic complexes based on p-phenylenediamine and 2,6-diaminopyri dine, is studied. The effect of procedures employed for synthesizing t he polymeric compounds and the influence of an additional thermal trea tment on their electrocatalytic properties are examined. It is found t hat the maximum effect is achieved when the p-phenylenediamine-based p olymeric complex obtained by condensation is used as the catalyst, The high-temperature treatment raises the discharge voltage of the cells and their usable capacity.
