%X Indium chloride (InCl3) as an electrolyte additive for primary aqueous Mg batteries is evaluated in this work in terms of its effect on discharge potential, self-corrosion rate and utilization efficiency of a newly developed Mg-0.15Ca anode. InCl3 addition to aqueous electrolyte leads to a more negative discharge potential but the enhancement weakens along with the consumption of In3+ to form In(OH)3 precipitates during the discharge process. Utilization efficiency of the anode is increased by adding InCl3 due to uniform anodic dissolution and suppressed self-corrosion with reduced chunk effect. Mg-air battery test results indicate that 10 mM InCl3 as electrolyte additive significantly enhances the cell voltage of aqueous Mg-air battery to 1.74 V and the specific energy based on anode weight loss to 2.26 kWh/ kg at 1 mA cm−2.
