Abstract: A binder containing a mixed powder including a polytetrafluoroethylene resin and a single-walled carbon nanotube. A weight ratio of the polytetrafluoroethylene resin to the single-walled carbon nanotube is 99.9:0.1 to 80:20. Also disclosed is a composition for producing an electrode in a form of a powder including the binder and an electrode active material substantially free of a liquid medium; an electrode mixture including the composition for producing an electrode; an electrode using the electrode mixture; a secondary battery having the electrode; a method for producing the binder; and a method for producing the electrode.

Abstract: The invention relates to electrotechnical industry, more particularly to lithium-ion batteries, and even more particularly to lithium-ion batteries with silicon-containing negative electrode (anode). The invention provides a method for producing an anode slurry (paste), an anode slurry (paste), a method for producing an anode for a lithium-ion battery, an anode for a lithium-ion battery, and a lithium-ion battery with a high initial specific capacity and a long cycle life with a large number of charge-discharge cycles over which the battery retains at least 80% of its initial capacity. This result becomes possible due to the presence in the anode material of bundles of single-walled and/or double-walled carbon nanotubes having a length of less than 5 ?m, together with bundles of single-walled and/or double-walled carbon nanotubes having a diameter of more than 500 nm and a length of more than 10 ?m.

Abstract: A composition for an electrochemical device, the composition containing a single-walled carbon nanotube, a binder and a solvent. The binder contains a fluorine-containing copolymer containing a vinylidene fluoride unit and a fluorinated monomer unit other than the vinylidene fluoride unit, and the content of the vinylidene fluoride unit in the fluorine-containing copolymer is 50.0 mol % or more relative to total monomer units. Also disclosed is a positive electrode mixture including the composition and a positive electrode structure including a current collector and the positive electrode mixture layer provided on one or both sides of the current collector.

Abstract: A metal foil has a surface with an added conductive layer comprising carbon nanotubes, wherein the conductive layer is applied so that the carbon nanotubes are arranged on the foil surface randomly and in an amount of 100 ng/cm2-10 ?g/cm2. A method for manufacturing the metal foil with a conductive layer of carbon nanotubes includes mixing carbon nanotubes with a solvent to form a suspension, applying the resulting suspension onto the metal foil surface so that the amount of carbon nanotubes on the surface is 100 ng/cm2-10 ?g/cm2 and they are arranged randomly, and then drying the suspension.
