6 FAQs about [Electroplating is required for lead-acid batteries]

How does electroplating lead affect battery energy density?

Upon completion of the electroplating process, the Ti/SnO 2 -SbO x /Pb grid was obtained. After electroplating lead onto a lead alloy grid, the grid weight increases, leading to a decrease of battery energy density. Electroplating lead onto pure titanium is also not compared in this context because the lead layer is only 100 μm thick.

Is lead electroplating possible?

Conventional lead electroplating is virtually impossible today because of environmental regulations. We have been advised to source this overseas; we would rather do it here. We are open to all suggestions, all ideas. Sorry, this RFQ for private contact is now outdated, but public technical replies are still welcome.

What are the problems with a lead acid battery?

Secondly, the corrosion and softening of the positive grid remain major issues. During the charging process of the lead acid battery, the lead dioxide positive electrode is polarized to a higher potential, causing the lead alloy positive grid, as the main body, to oxidize to lead oxide.
