A.K. Shukla, B. Hariprakash, in Encyclopedia of Electrochemical Power Sources, 2009 Iron electrodes also constitute the negative plates of the Fe–air battery. The Fe–air battery is an attractive concept as its theoretical specific energy is nearly three times that of Ni–Fe and four times that of lead–acid batteries.
In Electrical Systems and Equipment (Third Edition), 1992 The negative plate in a lead acid cell consists of a lead alloy lattice or grid in which the spaces of the grid are filled with chemically-active lead sponge.
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.
At this stage the positive and negative plates are identical. Once dry the plates are then stacked together with suitable separators and inserted in the battery container. An odd number of plates are always used, with one more negative plate than positive. Each alternate plate is connected together.
The capacity of the negative plate is determined by the energetic structure, which appears and disappears during each charge–discharge cycle. The useful life of the negative plate terminates when its capacity falls below an acceptable level.
