Abstract

This paper presents the results of an investigation into the properties of a lead-plated layer on the negative electrode grid of a foreign-manufactured high-capacity lead-acid battery. The material composition, the plating layer's thickness and structural morphology were all ascertained using SEM and EDX analysis techniques. This analysis served as a benchmark for developing a lead plating technology on expanded copper mesh using a lead fluoroborate bath. The findings have provided a technological regime for producing a lead plating layer using the electrolytic plating method that satisfies the structural morphology and thickness technical requirements of the foreign-made grid sample.
