| Abstract In alkaline batteries, zinc is one of the most commonly used and significant metals. It has been discovered that adding a small amount of indium or antimony as an alloying element to zinc enhances battery longevity while maintaining zinc's sacrificial protection. Electrochemically examined using Galvanostatic Charge Discharge techniques, charge-discharge performance for Zn, Zn-1% In, and Zn-1% Sb alloys in 6 M KOH solution. According to the charge-discharge data, introducing 1 percent In to Zn, the observable voltage is moved to a higher negative potential value. However, by adding the same quantity of Sb, this voltage is switched to a less negative direction. In comparison to Sb, however, greater capacitance values can be attained at 1% In. This suggests that 1% In alloying with Zn has a greater favorable impact on charge effectiveness and capacitance than 1% Sb alloying. Furthermore, compared to Zn-1 percent Sb alloy, the discharge duration of Zn-1 percent In alloy is longer. Finally, modest alloying of In or Sb with Zn can be considered viable composites for longer-lasting alkaline batteries | ||
