The method of making standby water-activated primary current sources, according to the invention, resides in that concurrently with hermetical sealing of the ends and edges of the negative electrodes, a flanged rim is provided along the perimeter of each of the negative electrodes, the height of said flanged rim being in excess of the thickness of the bipolar electrode and the separator. The flanged rim forms an angle from 90.degree. to 180.degree. with the electrode surface and is provided with at least one shoulder for passing the water and gases and for current leadout. The bipolar electrodes are interlaid with the separators, whereupon the adjacent portions of the flanged rims are welded together into an integral block of bipolar electrodes. The proposed method makes it possible to completely dispense with manual labor and simplify the production techniques.

A positive electrode for an air-depolarized alkaline primary cell comprising a catalyst for reduction of air oxygen, which catalyst is manganese dioxide, as well as carbon and a hydroxide solution of potassium, and is characterized, according to the invention, in that said catalyst is electrolytic or synthetic manganese dioxide of .gamma.-modification. The positive electrode of this invention can be employed in cylindrical and disc-type cells and alkaline electrolyte batteries.

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.
