During the charging process, the reactions at each electrode are reversed; the anode becomes the cathode and the cathode becomes the anode. During charging, given the high voltage, water is dissociated at the two electrodes, and gaseous hydrogen and oxygen products are readily formed leading to the loss of the electrolyte and a potentially explosive situation.
Under certain circumstances the lead sulphate products at both the electrodes achieve an irreversible state, making the recharging process very difficult. Pure lead is too soft to use as a grid material so in general the lead is hardened by the addition of 4 – 6% antimony. The function of the grid is to hold the active material and to conduct electricity between the active material and the battery terminals. Ball milling: Pieces of lead are put into a rotary mechanical mill, forming fine lead flakes, which are then oxidised in air and removed. Red lead (Pb3O4) can also be added to the PbO formed by these methods, as it is more conductive.
The oxide is mixed with water, sulphuric acid and a mixer, and then mixed to form a paste.


The simplest cell would consist of one cathode plate, one anode plate and a separator between them.

The most common is the SLI battery used for motor vehicles for engine Starting, vehicle Lighting and engine Ignition, however it has many other applications (such as communications devices, emergency lighting systems and power tools) due to its cheapness and good performance. Strips of lead foil with coarse cloth in between were rolled into a spiral and immersed in a 10% solution of sulphuric acid. These act as grain refiners, decreasing the grain size of the lead and thereby increasing its hardness and strength.
This is often used for telephone applications, and for no maintenance automotive batteries, since a more stable battery is required.
Each droplet reacts with the air to form an oxide layer, giving 70 – 85% lead oxide.


Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Import charges previously quoted are subject to change if you increase you maximum bid amount. The cell was further developed by initially coating the lead with oxides, then by forming plates of lead oxide by coating an oxide paste onto grids.
The molds are closed and filled with sufficient molten lead to fill the mold, leaving some excess to form a sprue, which is then removed by cutting or stamping. The separators are usually cellulose, PVC, rubber, microporous polyethylene or non-woven polypropylene.
If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. The tabs that are fixed to the plates are cast, then punched on between the layers and welded together.
The plates are suspended inside the case, which is filled with electrolyte in order to activate it.
