    Anode Lead
AI Thread Summary
Using lead strips for anodes in lead-acid batteries raises questions about the feasibility of electrolysis to oxidize the surface to lead dioxide (PbO2). While this method appears straightforward, it has not been widely adopted, possibly due to concerns about the durability of the lead dioxide layer. The original method of using bare lead in battery construction has evolved, with modern techniques focusing on plating lead dioxide to enhance performance. The main challenge lies in ensuring that the PbO2 generated is robust enough to withstand operational stresses, such as high current densities and thermal fluctuations, without flaking off. Additional resources, including patents and recipes, are available online for those interested in exploring this topic further.

I usually plate lead dioxide on carbon to form my anodes, however, I was wondering if anyone knew why one can't use a lead strip and let electrolysis oxidize the surface to lead dioxide? It is too simple for it not to be used already. But I did make a set of lead acid batteries by just using the lead strips with no lead dioxide and it worked fine. I was wondering if anyone had some insight on the subject.

I believe using bare lead was the original method of making batteries, plating with oxide is relatively new way of making batteries that are already charged even before they are filled with acid.
 
The problem is much less one of generating PbO2, but generating it in a way
that makes it sufficiently hardy to not deteriorate (i.e. flake off) during use as
an anode, possibly with high current densities, thermal gradients etc. etc.

You can find some patents and recipes by googling.

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
