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. The active materials are held in nickel-plated steel tubes or perforated pockets.
A nickel-iron (NiFe) battery is a flooded battery that stores electricity through oxidation and reduction reactions. A battery that is ‘flooded' is one that has a flowing electrolyte. Nickel iron batteries usually contain an alkali electrolyte and water as the aqueous components.
Durability and lifespan of a nickel-iron cell are much higher than that of a lead acid battery, but still, the nickel-iron battery has lost its popularity because of its high manufacturing cost. Let’s have a look at some specific features of nickel-iron (Ni-Fe) or Edison battery.
Edison had outfitted his car with a new type of battery that he hoped would soon be powering vehicles throughout the country: a nickel-iron battery.
A group of researchers at Stanford has significantly improved the performance of nickel-iron batteries, which may lead to new applications for this venerable battery.
The nickel-iron (Ni-Fe) battery is a century-old technology that fell out of favor compared to modern batteries such as lead–acid and lithium-ion batteries.
Nickel–iron batteries have been successfully developed and commercialized in the early 20th century. Nickel–iron or ‘NiFe’ cells are secondary batteries that fell out of favor with the advent of cheaper lead acid cells.
A team of chemists at Stanford have created a nickel-iron battery prototype that can charge and discharge in seconds using carbon nanostructures.
In this article, I am going to discuss the nickel iron battery construction, working principle, and compare its features with a lead-acid battery. So keep reading. The Nickel-Iron alkaline cell was developed by an American scientist Thomson A. Edison in 1909.
The nickel-iron battery (NiFe) uses an oxide-hydroxide cathode and an iron anode with potassium hydroxide electrolyte that produces a nominal cell voltage of 1.20V. NiFe is resilient to overcharge and over-discharge and can last for more than 20 years in standby applications.
