A b s t r a c t Zinc is one of the predominantly utilized metals in alkaline batteries. The addition of a trace amount of indium as an alloying element to zinc retards the rate of corrosion and promotes the sacrificial protection of zinc. The corrosion behavior of Zn and ZneIn alloy at various In content (0.5% and 1%, ... Read more

Abstract Zinc metal is an important element that can be used for long-life alkaline batteries. In this work, it is found that the addition of minor amounts of indium can slow down the corrosion rate and maintain the sacrificial protection of Zn in the alkaline media of batteries. The performance of anodic dissolution and passivation for Zn and Zn-In bimetal ... Read more

Abstract The processes of hydrogen evolution reaction and anodic dissolution of zinc and zinc antimony alloys with different antimony amounts (0.5 and 1%) immersed in 6 M KOH were tested via many electrochemical methods as Tafel polarization, cyclic voltammetry (CV), impedance spectroscopy (EIS), and charge-discharge. Newly formed phases, the morphology of the surface, and chemical composition for Zn and ZneSb ... Read more

ABSTRACT Zinc is one of the most important metals used in alkaline batteries. The addition of a trace amount of indium as an alloying element to zinc reduces the rate of corrosion and promotes the sacrificial protection of zinc. The corrosion behavior of Zn and Zn-In alloy at various In content (0.5% and 1%, In/Zn mass fraction) in 6 M ... Read more

Abstract Zinc is an important metal that can be used for alkaline batteries. The addition of very small amounts of indium, can slow down the corrosion rate, maintain sacrificial protection and improve charge and discharge properties of zinc in alkaline media for batteries application. The electrochemical and corrosion behavior of Zn and Zn−In alloys with different indium contents (0.5% and ... Read more

Abstract The corrosion and corrosion inhibition of Pb and Pb–In alloys in HCl solution, were investigated. The study was performed in the absence and presence of the phytic acid (PA) inhibitor using potentiodynamic polarization and electrochemical impedance spectroscopy measurements, and complementary by scanning electron microscope (SEM) and X-ray spectroscopy analysis (EDX) investigations. The obtained outcomes showed that the PA is ... Read more

Abstract ABSTRACT THE PROCESSES OF HYDROGEN EVOLUTION REACTION AND ANODIC DISSOLUTION OF ZINC AND ZINCANTIMONY ALLOYS WITH DIFFERENT ANTIMONY AMOUNTS (0.5 AND 1%) IMMERSED IN 6 M KOH WERE TESTED VIA MANY ELECTROCHEMICAL METHODS AS TAFEL POLARIZATION, CYCLIC VOLTAMMETRY (CV), IMPEDANCE SPECTROSCOPY (EIS), AND CHARGE-DISCHARGE. NEWLY FORMED PHASES, THE MORPHOLOGY OF THE SURFACE, AND CHEMICAL COMPOSITION FOR ZN AND ZNESB ... Read more

ABSTRACT THE EFFECT OF IN CONTENT ON THE ELECTROCHEMICAL AND CORROSION BEHAVIOR OF PB-IN ALLOY IN H2SO4 ELECTROLYTE IS INVESTIGATED BY TAFEL PLOT, ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY (EIS) AND CYCLIC VOLTAMMETRY METHODS. MEASUREMENTS ARE CONDUCTED UNDER DIFFERENT EXPERIMENTAL CONDITIONS. THE RESULTS OF BOTH TAFEL PLOT EXTRAPOLATION AND ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY (EIS) MEASUREMENTS EXHIBIT THE SAME TREND, IN CONCERN THE CORROSION RATE ... Read more

ABSTRACT THE ELECTROCHEMICAL AND CORROSION BEHAVIOR OF PB AND PB-IN ALLOYS IN BOTH PHOSPHORIC AND SULFURIC ACID SOLUTIONS CONTAINING VARIOUS CONCENTRATIONS OF PHOSPHORIC ACID (0.05 TO 0.20 M) AT DIFFERENT TEMPERATURES WAS STUDIED. TAFEL PLOT AND ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY (EIS) TECHNIQUES WERE USED TO OBTAIN THE EXPERIMENTAL DATA, AND THE CORROSION PRODUCTS FORMED ON THE SURFACE WERE CHARACTERIZED BY SCANNING ...

Abstract: The addition of phosphoric acid into sulfuric acid solution is mentioned to be helpful in the reduction of sulfation after deep discharge of lead-acid battery. The anodic behavior of Pb and Pb−In alloys was studied in pure phosphoric acid and sulfuric acid containing various concentrations of phosphoric. The electrochemical measurements were performed using potentiodynamic, potentiostatic and cyclic voltammetric techniques. ... Read more
