“…The ultrafine‐grained alloy microstructure of ECA samples prompted uniform corrosion morphology, whereas the non‐ECA samples showed intergranular corrosion (Figure 23). [305] Their results showed that the grain size reduction benefited pure Al but not Al alloys. This can be due to the more facile diffusion of the passivating oxides that happened with pure Al than the alloys, as grain size reduction can have either positive or negative effects on electrochemical corrosion resistance [314]…”

“…Due to abundance, relative inexpensiveness, environmental friendliness and desirable specific capacity and standard electrode potential, Al-air batteries attracted significant research attention. [305] The most studied mitigation strategy for Al anode corrosion in MABs is alloying. [306,307] Peng et al have shown that 0.1 wt % Mn added Al-Mn anodes exhibited the optimum discharge efficacy for an Al-air battery.…”

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.

“…Researchers have reported that grain size could affect battery performance. [63][64][65][66] A smaller grain size is favorable for enhancing the working voltage and specic capacity of the Al anode. However, the former tests show that A6061 which has a larger grain size presents better electrochemical properties.…”

This study compared the electrochemical performances of porous surface electrodes obtained by the salt casting process against a smooth surface electrode. Potentiodynamic polarization test, linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy (EIS) tests of porous and smooth Al electrodes were performed using 0.5 M NaOH solution. According to the Tafel analysis, the Jcor value of the Al‐porous electrode was measured as 3.23 mA cm−2, which is approximately 55 % higher than the Al‐smooth electrode. The Ecor value was more negative for the Al‐porous electrode. Results of the low charge transfer resistance (2.2 Ω) of the Al‐porous electrode compared to the Al‐smooth electrode (2.8 Ω) concluded that the porous surface was increased the current density by increasing charge transport due to higher surface area. The galvanostatic discharge tests of the electrodes were carried out in an Al‐air battery test cell using a graphite carbon air cathode. As a result, the power density of the Al‐porous electrode was approximately 42 % higher than the Al‐smooth surface electrode.
