FIELD: electricity.
SUBSTANCE: to produce active mass of electrodes, aqueous solutions of polyacrylates and their copolymers are used as binder. Mixing of components is carried out simultaneously with ultrasonic dispersion, binder is represented by an aqueous dispersion of polyacrylate or copolymer of sterol and acrylate at the following ratios of mix components, % (wt % of dry substance). Active material: 77-97. Acetylene technical carbon: 1-12%. Aqueous dispersion of polyacrylate or sterol-acrylate: 2-12%, and drying of electrodes is carried out down to residual moisture of 0.005%.
EFFECT: increased specific discharge capacity, reduced ecological risk and lower prime cost of explosion safety.
