Inhibitive Action of Sulfide Ions on Corrosion and Enhancing Charge‐Discharge Efficiency of Zinc and Zinc‐Indium Alloy as Anode for Alkaline Batteries

Autor: Hany M. Abd El‐Lateef, Mahmoud Elrouby, Hoda A. El‐Shafy Shilkamy, Abd El‐Rahman El‐Sayed

Publikováno v: ChemElectroChem, Vol 11, Iss 7, Pp n/a-n/a (2024)

Abstract The obtained data reveal that the coverage of surface (θ) and protection efficiency (η%) for the studied electrodes increases gradually as the inhibitor concentration increases. Tafel plot is carried out at variant temperatures in the inve

The passivity breakdown of zinc antimony alloy as an anode in the alkaline batteries

Autor: Abd El-Rahman El-Sayed, Hoda A. El-Shafy Shilkamy, Mahmoud Elrouby

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-13 (2022)

Abstract Zn is utilized as an anode in alkaline batteries because of its propensity to produce a passive colloidal layer on its surface. Then the surface should be reactivated in the passive region. Therefore, the passive state on the surface can be

Tracing the influence of small additions of antimony to zinc on the hydrogen evolution and anodic dissolution processes of zinc as anodes for alkaline batteries application

Autor: Abdel-Rahman El-Sayed, Hoda A. El-Shafy Shilkamy, Mahmoud Elrouby

Publikováno v: International Journal of Hydrogen Energy. 46:31239-31252

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 voltammet

The impact of indium metal as a minor bimetal on the anodic dissolution and passivation performance of zinc for alkaline batteries: part I—potentiodynamic, potentiostatic, XRD, SEM, and EDAX studies

Autor: Abdel-Rahman El-Sayed, Hoda A. El-Shafy Shilkamy, Mahmoud Elrouby

Publikováno v: Journal of Solid State Electrochemistry. 25:2161-2174

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 alkalin
