Abstract

Abstract: The composition of the rolled then annealed AT61 (Mg-6%Al-1%Sn) and AP65 (Mg-6%Al-5%Pb) magnesium alloy anodes were analyzed, the effects of 3.5wt% and 7.0wt% NaCl electrolytes on the electrochemical properties of two magnesium alloys were studied by using X-ray diffraction, scanning electron microscopy, energy spectrum analyzer, electrochemical measurement and battery tester. The results show that the Mg ₁₇ Al ₁₂ phase diffuses into the matrix of AT61 and AP65 magnesium alloys after homogenization heat-treatment at 430 ℃ for 16 h; compared with 3.5wt% NaCl electrolyte, the discharge performance of magnesium alloy anodes have been improved in 7.0wt% NaCl electrolyte while magnesium alloy-air batteries have enhanced discharge stability.
