ABSTRACT:
Disclosure is made of a method for producing a coated iron electrode of an alkaline accumulator. Into an active mass comprising black iron ore concentrate, iron oxide, synthetic fiber, ferrous sulphide and an aqueous solution of nickel sulphate there is introduced an aqueous solution of surface-active compounds. The active mass is spread on a steel-band grid, which is followed by drying and treating the electrode thus produced with a binder, the binder being a suspension of sodium or ammonium bicarbonates, or lithium hydroxide in an epoxide resin solution with an addition of a hardener of the polyethylenepolyamine type. Upon drying, the electrode thus produced possesses improved electric characteristics and mechanical strength, the weight of the electrode is reduced, and its service life is prolonged.
