Abstract
The effect of fluorine-containing surface-active substances (FSAS) on the electrochemical behavior of lead in sulfuric acid is discussed. Th e adsorption of cationic FSAS is shown to be strengthened with the inc reasing cathodic polarization of lead. The introduction of FSAS into t he electrolyte gives rise to an increase both in the overpotential of cathodic hydrogen evolution and in the discharge capacitance of the ne gative electrode of a lead battery, the increase being strengthened as the temperature decreases.
