“…The electrochemical behaviour of coatings was studied in an aerated reference corrosive solution (D1384-87 ASTM standard water: Na 2 SO 4 , 148 mg/l; NaHCO 3 , 138 mg/l; NaCl, 165 mg/l [16], noted ASTM water) using a three electrode electrochemical cell [17,18]. This solution was chosen because of its moderate aggressiveness, and the results obtained can be well correlated with exposure over a long period to atmospheric conditions [19].…”

“…Moreover, the knowledge of the tin solubility in lead-calcium solid solution is crucial to develop any alloy compositions for acid battery applications. In particular, the tin content in aPb after aging process increases the corrosion resistance in sulfuric acid of these ternary alloys [24]. Otherwise, it must be noticed that the Ca solubility in aPb drops drastically with the temperature decrease: the calcium solubility is three hundred times less at 300 K than at 573 K ( Fig.…”

“…[4][5][6][7] Addition of Sn in the grid alloys is effective in recovery after overcharging, on long standing and in improving the corrosion resistance. [8][9][10] Typical composition of Pb-Ca-Sn alloys is 0.08-0.12% Ca and 0.2-0.4% Sn for negative grids while as positive grids 0.04-0.06% Ca and 1.0-1.2% Sn is used. 11) Research studies to improve the performance of Pb-Ca-Sn grids by controlling the alloying elements and heat treatments received atten-tion.…”

:The electrochemical performance of positive pole grids of lead-acid batteries made of Pb-0.08%Ca-1.1%Sn alloys without and with 0.1 wt% of each of Cu, As or Sb and with 0.1 wt% of Cu, As and Sb combined was investigated by electrochemical methods in 4.0 M H 2 SO 4 . The corrodibility of alloys under open-circuit conditions and constant current charging of the positive pole, the positive pole gassing and the self-discharge of the charged positive pole were studied. All impurities (Cu, As, Sb) were found to decrease the corrosion resistance, R corr after 1/2 hour corrosion, but after 24 hours an improvement in R corr was recorded for Sb containing alloy and the alloy with the three impurities combined. While an individual impurity was found to enhance oxygen evolution reaction, the impurities combined significantly inhibition this reaction and the related water loss problem was improved. Impedance results were found helpful in identification of the species involved in the charging/discharging and the self-discharge of the positive pole. Impurities individually or combined were found to increase the self-discharge during polarization (33-68%), where Sb containing alloy was the worst and impurities combined alloy was the least. The corrosion of the positive pole grid in the constant current charging was found to increase in the presence of impurities by 5-10%. Under open-circuit, the self-discharge of the charged positive grids was found to increase significantly (92-212%) in the presence of impurities, with Sb-containing alloy was the worst. The important result of the study is that the harmful effect of the studied impurities combined was not additive but sometimes lesser than any individual impurity.
