Abstract	Abstract Mg–Al–Sn alloy is one of the new developed anode materials for seawater activated batteries. The potentiodynamic polarization, galvanostatic discharge and electrochemical impedance spectroscopy of Mg–6%Al–1%Sn and Mg–6%Al–5%Sn (mass fraction) alloys in seawater were studied and compared with the commercial AZ31 and AP65 alloys. The results show that the Mg–6%Al–1%Sn alloy obtains the most negative discharge potential of average –1.611 V with a electric current density of 100 mA/cm 2 . EIS studies reveal that the Mg–Al–Sn alloy/seawater interfacial electrochemical process is determined by an activation controlled reaction. The assembled prototype batteries with Mg–6%Al–1%Sn alloy as anodes and AgCl as cathodes exhibit a satisfactory integrated discharge properties.
