The negative and positive lead battery plates conduct the energy during charging and discharging. This pasted plate design is the generally accepted benchmark for lead battery plates. Overall battery capacity is increased by adding additional pairs of plates.
In the charged state, the positive active-material of the lead–acid battery is highly porous lead dioxide (PbO 2). During discharge, this material is partly reduced to lead sulfate. In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead.
The negative and positive lead battery plates conduct the energy during charging and discharging. This pasted plate design is the generally accepted benchmark for lead battery plates. Overall battery capacity is increased by adding additional pairs of plates. A pure lead grid structure would not be able to support the above framework vertically.
Sci., 9 (2014) 4826 - 4839 Positive plates for the carbon lead-acid battery (CLAB) with porous carbon grids coated with lead have been prepared and tested. Lead coating thickness in the range between 20 and 140 micrometers has been shown to positively influence the discharging profile and the cyclic lifetime of the plates.
In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead. Whereas this so-called ‘Planté plate’ is still in demand today for certain battery types, flat and tubular geometries have become the two major designs of positive electrode.
Assembling the spines, gauntlets, lead oxide, and bottom bar together makes a positive plate. Volume changes during discharge and charge are mostly compensated by a high mass porosity, and gas bubbles help to distribute remaining free particles in the cell. Pressing the PbO corrosion layer onto the grid surface also helps to protect the lead grid
The layer between the grid of the positive plate in the lead-acid battery and the positive active mass (PAM) is a complex mixture of lead oxides and sulfates formed during plate curing and formation. The layer is also transforming during the cyclic charging/discharging of the plate.

The positive plates gradually turn the chocolate brown color of Lead Dioxide, and the negative turn the slate gray of ''spongy'' lead. Such a cell is ready to be used. One of the problems with the plates in a lead-acid battery is that the plates change size as the battery charges and discharges, the plates increasing in size as the active material absorbs sulphate …

During battery discharge, the lead dioxide (PbO 2) active material at the positive plate is reduced (hence the term ''cathode''), the action being facilitated by the availability of electrons that travel through the external electrical circuit. These electrons are generated at the negative plate where the sponge lead active material is oxidized (hence the term ''anode''). Note that the ...
