Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.
Linear sweep voltammetric (LSV) and impedance studies of lead/antimony binary alloys (0–12% Sb) are described. The formation of a solid antimony-containing species in close contact with a passivating layer of lead sulphate at sufficiently positive potentials (before lead dioxide formation) is indicated. In the presence of antimony, changes in the characteristics of the passivating …

Corroded glaze, or a dusty or chalky grey residue on the glaze after the piece has been washed. Tableware in this condition may represent a serious lead hazard and should not be used. Lead is rarely found in plain white dishes. Lead-containing glazes or decorations on the outside of dishes or non-food surfaces are generally not a problem."
Despite the wide application of high-energy-density lithium-ion batteries (LIBs) in portable devices, electric vehicles, and emerging large-scale energy storage applications, lead acid batteries …
Lead–acid batteries are currently used in uninterrupted power modules, electric grid, and automotive applications (4, 5), including all hybrid and LIB-powered vehicles, as an independent 12-V supply to support starting, …
On the other hand, some of them have selective binding to specific macromolecules. The interaction of lead with aminolevulinic acid dehydratase and ferrochelatase is within this context. Reactions of other heavy metals with certain proteins were discussed as well. Some toxic metals including chromium, cadmium, and arsenic cause genomic instability.
the type of plates alternate inside the battery with the odd numbered from either direction (outside plates) being the ones made of lead. There is one more lead plate than lead oxide plate because the lead oxide is more reactive and tends to warp. Keeping a lead plate on either side ensures the plate is not warped in either direction.
It is well known that antimony, which is alloyed in the grids of the lead-acid battery to improve their castability, corrosion resistance, and strength, affects the properties of the battery in various ways. Of particular interest is its apparent beneficial effect on the cycle life of the positive plate. It has been suggested that antimony is responsible for maintaining a minimum concentration ...

The lead-acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o…
