FIELD: batteries.
SUBSTANCE: group of inventions relates to a composition for an electrochemical apparatus, a mixture of a positive electrode, a structure of a positive electrode, and an accumulator battery. Composition for an electrochemical apparatus includes single-walled carbon nanotubes, a binder, and a solvent, wherein 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 the total number of monomer units.
EFFECT: viscosity rise resistance if the electrode mixture even after a long time after production, low resistance and excellent adhesion to the current collector, flexibility and absence of springback.
