The electrodes in a lead-acid battery consist of spongy or porous lead for the negative electrode and lead oxide for the positive electrode. Both electrodes are immersed in an electrolytic solution of sulfuric acid and water.
The sulfuric acid provides the necessary ions that react with the lead to form lead sulfate, while the water helps to facilitate the chemical reactions. The electrodes in a lead-acid battery consist of spongy or porous lead for the negative electrode and lead oxide for the positive electrode.
Such applications include automotive starting lighting and ignition (SLI) and battery-powered uninterruptable power supplies (UPS). Lead acid battery cell consists of spongy lead as the negative active material, lead dioxide as the positive active material, immersed in diluted sulfuric acid electrolyte, with lead as the current collector:
To make a lead acid cell requires a glass or plastic container, lead roofing sheet that's unused but no longer shiny, 4M sulphuric acid, deionised water, petroleum jelly (eg vaseline) and some plastic to hold the lead plates in place. A hygrometer is used to achieve correct acid concentration.
Lead acid batteries are a simple technology, and have changed little since the 1800s. Battery banks for offgrid use are expensive, making home made battery banks an attractive option.
Harvesting from scrap lead acid batteries is a gamble, as any slight ionic contamination discharges the cells, making them useless. If you're determined to do it, make a test cell using a couple of little bits of lead, charge it in the prospective acid, and test its self discharge time.
The 2 electrodes are made of oxidised lead roofing sheet. Lead sheet can be rolled or folded to make an electrode with enough area. Just a little space should be left between the folds to …
