Investigation of stainless steel pickling liquor as a precursor for high Capacity battery electrode materials

Abstract

Stainless steel and battery manufacturing industries can be united for mutual economic and environmental benefits by utilizing stainless steel pickling liquor waste as a precursor for high energy iron fluoride based positive electrode materials in batteries.

Structural and magnetic properties of the low-dimensional fluoride β-FeF3(H2O)2·H2O

“…The ground-state of frustrated spin systems is therefore highly degenerate and new induced symmetries give rise to spectacular and often unexpected behavior at finite temperatures. 8 Further, the α-phase of FeF 3 ·3H 2 O can be used to synthesize semiconducting hematite nanowires for photoelectrochemical applications. One of the main reasons is that these systems usually present not only low dimensional properties but also magnetic frustration such as LiCuVO 4 , A 2 CuO 2 (A = Li, Na) and A 2 CuO 2 (A = Li, Na).…”

“…Especially iron(III) fluorides have attracted attention due to their high theoretical capacity and low cost. 8 Further, the α-phase of FeF 3 •3H 2 O can be used to synthesize semiconducting hematite nanowires for photoelectrochemical applications. 9 For all these reasons, additional work is required to investigate in more details the structural and magnetic properties of transition metal fluorides.…”

In vitrocorrosion studies of stainless-steel dental substrates duringPorphyromonas gingivalisbiofilm growth in artificial saliva solutions: providing insights into the role of resident oral bacterium

“…† As expected, these complexes composed of a mixture of simple metallic uoride (FeF 2 , FeF 3 , CrF 3 and NiF 2 ) and few ferrous oxides (Fe 2 O 3 and Fe 3 O 4 ). [58][59][60][61][62] Mouth rinsing products with uoride ions up to 250-10 000 mg L À1 concentrations promote the formation of these metallic uorides that eventually lead to remineralization between pH 3.5-7. This is slowly proceeded by corrosion of dental implants within this acidic NaF environment and at high concentration and pH.…”

Anionic Ordering and Thermal Properties of FeF3·3H2O

“…This highlights the need for a self-generated atmosphere in the stabilization of HTB-FeF 3 from FeF 3 •3H 2 O, because, as these values indicate, an uncontrolled reaction is likely to yield fluoride (α-FeF 3 ) and oxide phases as suggested by experimental observations. 5 It is worth noting that, within the HTB structure, the OH F1 and OH F2 substitutions were found to have the lowest formation energies compared to OH F3 and OH F4 , which indicates that the fluoride substitution by OH groups is favored within the hexagonal section of the network. A structural comparison between FeF 3 •3H 2 O and the HTB structure shows that the HTB F1 and F2 sites result from the condensation of the equatorial positions of FeF 6 and FeF 2 (H 2 O) 4 octahedra from FeF 3 •3H 2 O.…”
