Figure 8. (A) Schematic diagram of I₂-DMSO complex catalytic mechanism^[13]. (B) Discharge-charge profiles of Mg-air batteries with/without iodine at 60 ℃^[13]. (C) Schematic diagram of TEMPO-anion complex catalytic mechanism^[14]. (D) Discharge-charge profiles of the Mg-air battery incorporating PTMA in the cathode at 60 ℃^[14]. (E) Schematic diagram of BQ and Co(II)TPP dual redox mediator working mechanism^[15]. (F) Galvanostatic cycling of the Mg-air battery using BQ and Co(II)TPP dual redox mediators. The voltage profile of the working electrode (carbon paper) was measured against the counter electrode (Mg ribbon) in a two-electrode configuration^[15].
