Lead-acid battery electrolysis reaction

CO2 electrolysis to formic acid for carbon neutralization

To avoid carbonate precipitation for CO 2 electrolysis, developing CO 2 conversion in an acid electrolyte is viewed as an ultimately challenging technology. In Nature, Xia et al. recently explored a proton-exchange membrane system for reducing CO 2 to formic acid with a Pb–PbSO 4 composite catalyst derived from waste lead-acid …

In the discharged state, both the positive and negative plates become lead(II) sulfate (PbSO 4), and the electrolyte loses much of its dissolved sulfuric acid and becomes primarily water. Negative plate reaction Pb(s) + HSO 4(aq) → PbSO 4(s) + H (aq) + 2e The release of two conduction electrons gives the lead electrode a negative charge. As electrons accumulate, they create an electric field which attracts hydrogen ions and repels su…
