AI Customer ServiceThe positive active-material of lead–acid batteries is lead dioxide. During discharge, part of the material is reduced to lead sulfate; the reaction is reversed on charging. There are three types of positive electrodes: Planté, tubular and flat plates.
Most positive electrodes are flat plates and are employed in all starter batteries. The principal failure modes of the positive material are sulfation and premature capacity loss (PCL). In recent years, considerable progress has been made in enhancing the cycling performance of the positive plate.
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.
The positive electrode of the LAB consists of a combination of PbO and Pb 3 O 4. The active mass of the positive electrode is mostly transformed into two forms of lead sulfate during the curing process (hydro setting; 90%–95% relative humidity): 3PbO·PbSO 4 ·H 2 O (3BS) and 4PbO·PbSO 4 ·H 2 O (4BS).
Impurities in electrode materials can hinder electrochemical reactions, reduce capacity and accelerate degradation. Testing of electrode materials helps ensure purity and consistency, leading to optimal battery performance. Almost all the components of the battery are isolated and tested individually.
Although these processes are reversed during cell charge in secondary batteries, the positive electrode in these systems is still commonly, if somewhat inaccurately, referred to as the cathode, and the negative as the anode. Cathode active material in Lithium Ion battery are most likely metal oxides. Some of the common CAM are given below
