“…As for the etching time of 2 and 2.5 min, due to the full contact between the SSF surface and the etching solution, almost all of the surface is corroded, with corrosion byproducts (red circle in Figure 3f) formed on the surface, and the resultant hydrophilicity causes the increase of the difference between the polarity of SSF and the polarity of cathode material coating, which is not conducive to improving the adhesion between them. [ 29,30 ] The comparison of X‐Ray diffraction (XRD) patterns before and after etching can effectively confirm the generation of byproducts (Figure 4b). The diffraction peaks of the original SSF at 44.05° and 51.29° in 2 θ correspond to Cr 0.19 Fe 0.7 Ni 0.11 , while a new diffraction peak appears at 35.55° after long‐time etching, which proves that new byproducts are produced in addition to the original SSF composition.…”

Stainless steel foil, as the most commonly used current collector of aqueous zinc-ion battery cathode, has the advantages of low cost, good conductivity, good flexibility, lightweight, and so on. However, as a current collector, stainless steel foil still faces a series of challenges, such as easy shedding of active materials and large contact resistance. In this work, the surface of stainless steel foil is modified by physical grinding and chemical etching, and the influence of surface morphology of stainless steel foil on battery performance is investigated. The results show that the stainless steel foil treated with 0.2 M FeCl 3 þ 0.1 M HCl etching solution for 1 min has the best electrochemical performance, and its maximum discharge specific capacity is 2.14 times that of the original stainless steel foil. In addition, the assembled Zn-MnO 2 battery has good cycle stability and excellent rate performance, which can be attributed to the moderate roughness, effective contact area, and excellent conductivity of the modified stainless steel foil current collector.

Research and development on electrochemical energy storage and conversion (EESC) devices, viz. fuel cells, supercapacitors and batteries, are highly significant in realizing carbon neutrality and a sustainable energy economy. Component corrosion/ degradation remains a major threat to EESC device's long-term durability. Here, we provide a comprehensive account of the EESC device's corrosion and degradation issues. Discussions are mainly on polymer electrolyte membrane fuel cells, metal-ion and metal-air batteries and supercapacitors. Corrosion of bipolar plates/current collectors, carbon corrosion, electrode/ electrocatalyst degradation, and various mitigation approaches are detailed. The collective information provided could help develop EESC devices with better durability.

“…Electrochemical or chemical processes are used to turn the covered surface into a coating. The most common processes for forming conversion coatings are phosphatizing, 11 chromating, 12 and anodic oxidation. 13 The phosphate coating is resulted from immersing into or spraying the metal surface with acidic phosphate solutions.…”

Eco-friendly Silane-Based Coating for Mitigation of Carbon Steel Corrosion in Marine Environments

2023

Losses from corrosion contribute roughly 3–5% of the gross domestic product of developed nations, and among the many methods used to avoid corrosion, using silane-based coatings is seen to be of the biggest importance due to their low toxicity and superior adhesive qualities. It is essential to develop an anti-corrosion coating that is efficient, economical, and eco-friendly. The corrosion resistance and durability of various silane-based coatings such as 1,2-bis(triethoxysilyl)ethane (BTSE), bis[3-(triethoxysilyl)propyl]tetrasulfide (TESPT), and vinyltrimethylsilane (VTES) for carbon steel 1018 substrates were investigated in a high-salinity environment (4.5 wt % NaCl). The corrosion resistance performance was evaluated via potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques. Results revealed that the TESPT film (pH ≈ 7) has the best corrosion resistance performance on the carbon steel surface in the aggressive chloride environment, that is, 99.6%. The high corrosion resistance of the TESPT film is due to the hydrophobic nature of this silane, which leads to the formation of a stable and dense film. These results were supported by X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) analyses.
