| 摘 要： | 应用熔炼法制备含Li量为8.5%和14%的两种Mg-Li合金,分别由电势线性扫描、计时电流、交流阻抗和失重法等检测Mg-Li电极在NaCl溶液中的电化学特性,SEM观察其放电表面形貌.结果表明:Mg-14Li电极比Mg-8.5Li电极有较负的开路电位、更大的放电电流和较高的放电效率,但附着电极表面的疏松产物易于脱落.Mg-8.5Li电极的放电效率高于Mg-14Li电极的放电效率.两种电极在低恒电位放电电流效率均高于较高恒电位的放电电流效率.

| Abstract: | 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 electrod... |
