The basic components used in Nickel iron battery are nickel (III) hydroxide as the cathode, iron as anode and potassium hydroxide as the electrolyte. We add Nickel sulfate and Ferrous sulfide to the active material. The capacity of a Ni-Fe cell depends on the size and number of positive and negative plates.
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.
Nickel Iron Battery Definition: A Nickel Iron Battery, also known as an Edison Battery, is defined as a robust and long-lasting battery with high tolerance for overcharging and discharging. Efficiency: Nickel Iron Batteries have a charging efficiency of 65% and a discharging efficiency of 85%, which means they store and deliver energy effectively.
The nominal voltage per nickel iron cell is 1.4 V. The basic components used in Nickel iron battery are nickel (III) hydroxide as the cathode, iron as anode and potassium hydroxide as the electrolyte. We add Nickel sulfate and Ferrous sulfide to the active material.
The voltage characteristics of the Nickel Iron battery are similar to the lead-acid cell. A fully charged battery starts with an emf of 1.4 V, which slowly decreases to 1.3 V and then very slowly to 1.1 or 1.0 V during discharge. There is no lower limit for discharging emf, meaning the battery will eventually stop providing output.
These batteries have a lifespan of 30 to 100 years, much longer than the 10-year lifespan of lead acid battery. The nominal voltage per nickel iron cell is 1.4 V. The basic components used in Nickel iron battery are nickel (III) hydroxide as the cathode, iron as anode and potassium hydroxide as the electrolyte.
