The electrochemical behaviors of Mg-8Li-3Al-0.5Zn and Mg-8Li-3Al-1.0Zn in sodium chloride solution

► Zn contents would affect the performance of alloy anode of Mg-H2O2 semi fuel cells. ► The performance of Mg-8Li-3Al-0.5Zn is better than that of Mg-8Li-3Al-1.0Zn. ► Mg-8Li-3Al-0.5Zn alloy is suitable to use as anode of Mg-H2O2 semi fuel cells.
