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].
