When a lead-acid battery is discharged, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In the charged state, the main components of the positive and negative electrodes are lead sulfate [43, 44].
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.
Lead acid battery manufacturers apply this paste to a frame or grid structure that mechanically supports it. The electrolyte is then free to enter all the tiny holes in the sponge, thereby increasing the effective capacity of the battery. The negative and positive lead battery plates conduct the energy during charging and discharging.
The Ni-Cd battery uses nickel oxyhydroxide for the positive electrode and metallic cadmium for the negative electrode. The chemical reaction is as follows: As can be seen from this chemical reaction, there is a balance of reactions that implies that the electrolyte is always of the same concentration.
The most common approach nowadays involves turning the active material into a paste, with the appearance of a sponge full of tiny holes. Lead acid battery manufacturers apply this paste to a frame or grid structure that mechanically supports it.
