Elucidating the dependence of electrochemical behavior and discharge performance on the grain structure of lean Mg-0.3Bi-0.3Ag-0.3In anodes in primary Mg-air battery

Utilizing an electrolyte additive to modulate interfaces and enhance anode discharge performance in aqueous magnesium–air batteries

“…9(b) illustrates the distributions of η CE (chunk effect), η dis (discharge), and η HER (hydrogen evolution reaction) for the AZ31 Mg alloy during a 2 h discharge at a current density of 5 mA cm −2 . 53 The addition of Gly additives at different concentrations led to a reduction in η CE and η HER , thereby enhancing the anodic efficiency of the AZ31 anode. These findings align well with the results obtained from the examination of the substrate morphology after discharge (Fig.…”

“…Simultaneously, the scouring impact of hydrogen evolution on poorly connected substrates significantly reduced, thereby alleviating the chunk effect. 53 To thoroughly assess the degradation of capacity and the consistency of performance over time, batteries incorporating diverse electrolytes underwent rigorous intermittent discharge examinations (Fig. 9(c)).…”

Effects of Deformation Microstructures on the Electrochemical Properties of Mg-Hg-Ga Alloy Anode

“…Magnesium, which has negative standard electrode potential (−2.37 V vs standard hydrogen electrode), high faradic capacity (2.2 A h g −1 ), and abundant reserves, is a very desirable anode material. [3][4][5][6][7] However, pure magnesium has two obvious disadvantages as the anode of seawater battery. Firstly, the self-discharge rate of magnesium is high, which leads to a low efficiency of its utilization.…”
