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 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 can deliver 30 to 50 kW of energy per kilogram. Its charging efficiency is about 65%, meaning 65% of the input energy is stored as chemical energy. Its discharging efficiency is about 85%, so it can deliver 85% of the stored energy to the load.
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.
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 main reaction during charging of an iron electrode under basic conditions is the reduction of ferrous ion (Fe 2+) to elemental iron (Fe 0). Similarly, the oxidation of elemental iron to ferrous ions, occurs during discharge of the same electrode. Eq.
