Viktor Evmenievich Kononenko has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4123568
    Abstract: A method for manufacturing an electrode for an alkaline accumulator by applying an active mass to a metallic grid such as iron which includes preparation of an active mass comprising a black iron ore concentrate, iron oxide, synthetic fibre, ferrous technical iron, an aqueous solution of nickel sulfate, a surface active agent, and an aqueous solution of polyvinyl alcohol, said polyvinyl alcohol being heated prior to addition with a dehydrating agent such as a concentrated sulfuric acid in a ratio of 1:5 of sulfuric acid to polyvinyl alcohol. The resulting active mass is rubbed into a grid made of a steel band, and dried for 15 to 20 minutes at a temperature of from 110.degree. to 180.degree. C until the dehydration of polyvinyl alcohol corresponds to 25-30 mol.% of double bonds.

  • Patent number: 4021911
    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.
