Abstract:The electrochemical performance of lead-acid batteries made of Pb-Ca-Sn alloys with and without 0.1% of each of Cu, As, and Sb individually and combined in 4.0 M H 2 SO 4 in the absence and presence of 0.4 M H 3 BO 3 was studied. Both impurities and H 3 BO 3 were found to reduce the corrosion rate. Cyclic voltammetry revealed that the presence of impurities or H 3 BO 3 significantly retarded the formation of large crystal PbSO 4 . H 3 BO 3 increased the rates of oxygen and hydrogen evolution reactions for all alloys. Impedance measurement was used to quantify the amounts of PbSO 4 and PbO in the initial stage of the oxidation. H 3 BO 3 decreased the positive grid corrosion of all alloys, while impurities increased it. Although impurities increased the self-discharge during constant current discharge, H 3 BO 3 was found to decrease it, except for the alloy containing the 3 impurities and the Cu-containing alloy. Under open-circuit conditions, H 3 BO 3 increased significantly the self-discharge rate, but impurities were found to suppress it.

“…The effects of metal ions addition in the electrolyte and in the grid alloys on the battery electrical performance have been investigated by several authors [14][15][16][17][18][19][20][21]. The objective of the present paper is to determine the impact of the following ions (Mg 2+ , Al 3+ , Co 2+ , Sn 2+ and Sb 3+ ) on the properties of the active material of positive battery plates.…”

“…Pavlov e colaboradores 3 mostraram ser possível montar placas tubulares diretamente a partir do PbO 2 , desde que as placas tenham uma densidade mínima de 3,8 g/cm 3 . Essas placas foram capazes de fornecer até 80 Ah/kg de PbO 2 , 3 sendo que a capacidade específica de placas tubulares convencionais pode chegar a 120 Ah/kg de PbO 2 .…”

Recebido em 13/5/10; aceito em 16/7/10; publicado na web em 16/11/10 LEAD ACID BATTERIES TUBULAR POSITIVE ELECTRODES ASSEMBLED WITH NANOMETRIC ACTIVE MATERIAL. Conventional stationary lead acid batteries positive tubular plates have a specific capacity of about 120 Ah/kg. This value represents an active material utilization coefficient of 50%. The production of these plates includes some initial processes to generate the active PbO 2 from a precursor material. In the present work it will be presented a proper and novel methodology to assemble tubular plates directely with nanometric powder of PbO 2 particles. The utilization coefficient of these plates was about 80%, and they were able to endure more than 130 severe duty cycles. This high utilization coefficient is a higly desirable feature for electric vehicles batteries.
