✦ Synopsis

The influence of metallic ions Cd(II), Ni(II), Zn(I1) and Co(I1) on gassing and maintenance behaviour of both lead and lead dioxide electrodes has been studied using linear potential sweep voltammetry and charge and discharge curves. The experiments were made using a Pb-O.G%Ca alloy and commercial electrodes in 5 M H2S04 electrolytic solution. Charge efficiencies were enhanced and a lower maintenance was required when the battery contained Cd(I1) and Zn(I1) ions, but the opposite occurred with Ni(I1) and Co(I1) ions. ResumC L'influence de la presence des ions metalliques Cd(II), Ni(II), Zn(I1) et Co(I1) sur les reactions de degagement d'hydrogene, d'oxygene et d'oxydoreduction du plomb et de l'oxyde de plomb est Btudiee par voltamperometrie cyclique et de balayage lineaire de potentiel, ainsi que par trace des courbes de charge et decharge de chaque electrode. Les electrodes etudiees sont, d'une part, d'origine commerciale, et d'autre part, constitukes d'un alliage Pb-O.G%Ca l'electrolyte utilise est une solution d'acide sulfurique (5 M). En presence des ions Cd(I1) et Zn(II), l'efficacite de la charge est amelioree et la consommation d'eau est moindre. En presence des ions Ni(I1) et Co(II), des effets contraires sont obtenus.
