The Mg-Li electrodes containing 8.5% and 14% Li were prepared using an induction melting method.Their electrochemical behavior in NaCl solution was investigated by means of potentiodynamic polarization,potentiostatic oxidation,electrochemical impedance technique and mass-loss measurements.The morphology of the electrodes after discharge was examined using scanning electron microscopy.The Mg-14Li electrode showed more negative open circuit potential and higher discharge current density than Mg-8.5Li electrode.The oxidation products of Mg-14Li loosely attached on the electrode surface and peeled off easily.The Mg-8.5Li exhibited higher utilization efficiency.Both electrodes gave higher utilization efficiencies when discharged at lower anodic potential.
