Organic/inorganic double solutions for magnesium–air batteries

Abstract

In order to limit the anode corrosion and improve the battery activity, magnesium–air batteries with organic/inorganic double solutions (0.5 M Mg(ClO4)2–N,N-dimethylformamide (DMF)/0.6 M NaCl–H2O, 0.5 M Mg(ClO4)2–acetonitrile (AN)/0.6 M NaCl–H2O) were prepared.

Corrosion and Materials Degradation in Electrochemical Energy Storage and Conversion Devices

“…The application of Mg for MABs is hindered primarily by its severe corrosion susceptibility [326–346] . Electrode design modification via alloying is the most studied approach for enhancing corrosion resistance and battery performance [326,327] .…”

“…Several works investigated novel electrolytes, electrolyte additives, corrosion inhibitors or protective coatings for improved corrosion resistance and battery performance [327,337–346] . Deyab et al.…”

“…The NaNO 3 electrolyte was more suitable to maximize the Mg 2+ dissolution via faradaic reactions suitable for MABs [327] . Novel electrolyte systems were explored by a few studies [339] …”

“…[336] Several works investigated novel electrolytes, electrolyte additives, corrosion inhibitors or protective coatings for improved corrosion resistance and battery performance. [327,[337][338][339][340][341][342][343][344][345][346] Deyab et al showed that a conductive nanocomposite coating of PAni and functionalized CNTs extended the discharge time of Mg anodes in 3.5 wt % NaCl and resulted in a slow operating voltage drop in an assembled cell. [338] For better battery performance, the electrolyte or inhibitor should assist in forming a passive protective layer preventing crucial corrosion; however, it should not hinder the Mg 2 + dissolution required for the battery reactions.…”

Influence of sodium 5-sulfosalicylate as a corrosion inhibitor in NaCl electrolyte on enhanced performances of Mg-air batteries

“…Nowadays, more and more studies are focused on the electrolyte. Wang's group [22] applied organic/inorganic mixed solution as electrolyte for Mg-air batteries. Höche et al employed Fe 3+ complexing agent, like salicylate, to boost battery performance [23].…”
