The construction of a lead acid battery cell is as shown in Fig. 1. It consists of the following parts : Anode or positive terminal (or plate). Cathode or negative terminal (or plate). Electrolyte. Separators. Anode or positive terminal (or plate): The positive plates are also called as anode. The material used for it is lead peroxide (PbO 2).
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.
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 active components involved in lead-acid storage battery are negative electrode made of spongy lead (Pb), positive electrode made of lead dioxide (PbO 2 ), electrolyte solution of sulphuric acid (H 2 SO 4 ) and Separator which is used to prevent ionic flow between electrodes and increasing of internal resistance in a cell.
Current collectors in lead acid batteries are made of lead, leading to the low-energy density. In addition, lead is prone to corrosion when exposed to the sulfuric acid electrolyte. SLI applications make use of flat-plate grid designs as the current collectors, whereas more advanced batteries use tubular designs.
The release of two conduction electrons gives the lead electrode a negative charge. As electrons accumulate, they create an electric field which attracts hydrogen ions and repels sulfate ions, leading to a double-layer near the surface.
The alternate plates then constitute alternating positive and negative electrodes, and within the cell are later connected to one another (negative to negative, positive to positive) in parallel. The separators inhibit the plates from touching …
