Since a single cell produces a very low amount of current and voltage, many cells are connected in series and parallel to increase current and voltage rating of a nickel-iron battery respectively. When the battery is fully charged, its positive plate is of Ni (OH) 4 and its negative plate is of iron (Fe).
The nickel-iron battery construction is shown in Figure. A Nickel-Iron cell has two plates. The active material of the positive plate is Ni (OH) 4 and the negative plate is of iron (Fe). The electrolyte is a solution of potassium hydroxide (KOH) with a small addition of lithium hydrate (LiOH) which increases the capacity of the cell.
Negative plates are connected to the container. Since a small quantity of electrolyte is used, therefore, it is quite compact. Since a single cell produces a very low amount of current and voltage, many cells are connected in series and parallel to increase current and voltage rating of a nickel-iron battery respectively.
Nickel–iron batteries manufactured between 1972 and 1975 under the "Exide" brand originally developed in 1901 by Thomas Edison. The nickel–iron battery (NiFe battery) is a rechargeable battery having nickel (III) oxide-hydroxide positive plates and iron negative plates, with an electrolyte of potassium hydroxide.
Spilling of electrolyte (KOH) is not harmful. Whereas in the case of lead-acid battery, it is harmful. Since the specific gravity of the electrolyte (KOH) does not change while charging and discharging, therefore a nickel-iron battery is not damaged if it is left in a fully discharged condition for a considerable time of period.
