Abstract
A method of producing a thickened electrolyte for a primary cell, which involves mixing, at about room temperature, aqueous solutions of calcium chloride, zinc chloride, and ammonium chloride with a tanning agent, such as chromium sulphate, and starch as a thickening agent, aging the resulting mixture until a thickened electrolyte with a compressive strength of 0.05-0.85 kg/cm.sup.2 is obtained and pressing said electrolyte through at least one drawhole at a rate of at least 0.05 m/sec, the resulting viscosity of the electrolyte being sufficient to apply a layer of the thickened electrolyte to the negative electrode of a primary cell.
