The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
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.

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 lead–acid batteries
The largest use of lead in the early 21st century is in lead–acid batteries. The lead in batteries undergoes no direct contact with humans, so there are fewer toxicity concerns. [r] People who work in lead battery production or recycling plants may be exposed to lead dust and inhale it. [237] The reactions in the battery between lead, lead ...
An aqueous battery is an electric battery that uses a water-based solution as an electrolyte. The aqueous batteries are known since 1860s, do not have the energy density and cycle life required by the grid storage and electric vehicles , [ 1 ] but are considered safe, reliable and inexpensive in comparison with the lithium-ion ones.

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 ...
