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. It is a very robust battery which is tolerant of abuse, (overcharge, overdischarge, and short-circuiting) and can have very lon. UsesMany railway vehicles use NiFe batteries. Some examples are and . The technology has regained popularity for applications. . When nickel-iron and lead batteries are fully charged they start to produce hydrogen. Which was seen as a disadvantage. But now nickel–iron batteries are being investigated for use as combined batteries and. . The ability of these batteries to survive frequent cycling is due to the low solubility of the reactants in the electrolyte. The formation of metallic iron during charge is slow because of the low solubility of the

Unintentional use of nickel can be traced back as far as 3500 BCE. from what is now Syria have been found to contain as much as 2% nickel. Some ancient Chinese manuscripts suggest that "white copper" (, known as baitong) was used there in 1700–1400 BCE. This Paktong white copper was exported to Britain as early as the 17th century, but the nickel content of this alloy was not discovered until 1822.

(Status of data on interactive map due to technical issues: 21. 2024). The United States hydrogen refueling network has 52 operational stations as of 2025—and it's shrinking. After Shell closed seven California stations in February 2024, the infrastructure that was supposed to revolutionize transportation is collapsing instead of expanding. Specifically, by the end of 2024, around 1,160 stations were up and running – an impressive milestone for an industry once. . Find hydrogen fueling stations in the United States and Canada.
