“…[316] Novel electrolyte system, such as high-strength agarose gel electrolyte, was studied. [317] Several works proposed various corrosion inhibitors that could enhance the Al anode corrosion resistance without affecting the battery performance, which include sodium stannate, [318] cerium chloride, [319] aromatic acids (benzoic acid, iso-phthalic acid, trimesic acid, amiono acids), [320] quaternary ammonium-type surfactants, [321] ellagic acid and Na 2 SnO 3 , [322] chrysanthemum coronarium leaves extract, [323] potassium sodium tartrate tetrahydrate and sodium stannate trihydrate, [324] and alkyl polyglucoside and K 2 SnO 3 . [325] Harchegani and Riahi showed that the pure Al anode selfcorrosion resistance was significantly improved by adding 1.0 wt % CeCl 2 .…”

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.

“…The most popular approach for protecting Al and its alloys in the air battery system is to combine organic and inorganic corrosion inhibitors and take advantage of their “synergy”. , This synergy is usually achieved by coupling organic inhibitors with inorganic inhibitors such as cerium chloride, potassium stannate, and sodium stannate − as they can inhibit the self-corrosion of Al anodes without any loss of activity. However, this method is more complicated and less eco-friendly than using only green organic corrosion inhibitors.…”

Screening a green corrosion inhibitor that can prevent Al anode corrosion and enhance the battery performance is highly significant for developing next-generation Al–air batteries. This work explores the non-toxic, environmentally safe, and nitrogen-rich amino acid derivative, N(α)-Boc-l-tryptophan (BCTO), as a green corrosion inhibitor for Al anodes. Our results confirm that BCTO has an excellent corrosion inhibition effect for the Al-5052 alloy in 4 M NaOH solution. An optimum inhibitor addition (2 mM) has increased the Al–air battery performance; the corrosion inhibition efficiency was 68.2%, and the anode utilization efficiency reached 92.0%. The capacity and energy density values increased from 990.10 mA h g–1 and 1317.23 W h kg–1 of the uninhibited system to 2739.70 mA h g–1 and 3723.53 W h kg–1 for the 2 mM BCTO added system. The adsorption behavior of BCTO on the Al-5052 surface was further explored by theoretical calculations. This work paves the way for constructing durable Al–air batteries through an electrolyte regulation strategy.
