FIELD: chemical current supplies; electrolytes used for lead-acid batteries.
SUBSTANCE: electrolyte is doped with polyacrylamide in the amount of 0.001 to 6.0 mass percent per amount of electrolyte. Polyacrylamide added to electrolyte depends for its action on its coagulating properties and on increase of electrolyte viscosity which holds powdered active masses and products of reaction on electrolyte surface thereby preventing their fall-down, creeping, and wash-out. Polyacrylamide is introduced in the form of its aqueous solution before or after battery is filled with electrolyte to function as its additive.
EFFECT: improved operating characteristics and enhanced service life of batteries.
