  2. Lead–acid battery - Wikipedia

    en.wikipedia.org/wiki/Leadacid_battery

    About 60% of the weight of an automotive-type leadacid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. [8] For example, there are approximately 8.7 kilograms (19 lb) of lead in a typical 14.5-kilogram (32 lb) battery.

    en.wikipedia.org/wiki/Lead_oxide

    Less common lead oxides are: Lead sesquioxide, Pb 2 O 3, which is a lead (II,IV) oxide as well (lead(II) metaplumbate(IV) [Pb 2+][PbO 2− 3]), reddish yellow; Pb 12 O 19, monoclinic, dark-brown or black crystals; The so-called black lead oxide, which is a mixture of PbO and fine-powdered Pb metal and used in the production of leadacid batteries

  6. Lead dioxide - Wikipedia

    en.wikipedia.org/wiki/Lead_dioxide

    It is an oxide where lead is in an oxidation state of +4. [1] It is a dark-brown solid which is insoluble in water. [2] It exists in two crystalline forms. It has several important applications in electrochemistry, in particular as the positive plate of lead acid batteries.

  7. Lead (II,IV) oxide - Wikipedia

    en.wikipedia.org/wiki/Lead(II,IV)_oxide

    Nitric acid dissolves the lead(II) oxide component, leaving behind the insoluble lead(IV) oxide: Pb 3 O 4 + 4 HNO 3 → PbO 2 + 2 Pb(NO 3) 2 + 2 H 2 O. With iron oxides and with elemental iron, lead(II,IV) oxide forms insoluble iron(II) and iron(III) plumbates, which is the basis of the anticorrosive properties of lead-based paints applied to ...

  8. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.

  9. Lead(II) oxide - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_oxide

    Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O. PbO occurs in two polymorphs : litharge having a tetragonal crystal structure , and massicot having an orthorhombic crystal structure .
