Mg-Zn-Cu系合金作为镁电池负极材料的性能
Performance of Mg-Zn-Cu Series Alloy as Anodic Material for Magnesium Battery
摘 要
针对AZ31镁合金作为镁电池负极存在放电电压低、放电容量低及放电稳定性差等问题，选择Mg-Zn-Cu系合金作为研究对象，采用XRD、SEM、电化学测试及恒流放电测试等方法，研究了合金元素含量对材料电化学性能及放电性能的影响。结果表明：相比于AZ31镁合金，Mg-2.00Zn-1.87Cu（质量分数）合金的放电稳定电压更高、放电容量更大，具有更好的放电性能。

Abstract
There are some problems such as low discharge voltage, low discharge capacity and poor stability of discharge in magnesium battery, in which AZ31 alloy is served as cathode. Mg-Zn-Cu series alloy was chosen as a research object, the effects of alloying elements on the electrochemical performance and discharge performance of Mg-Zn-Cu series alloy were investigated by XRD, SEM, electrochemical tests and constant current discharge tests. The results showed that Mg-2.00Zn-1.87Cu (wt.%) magnesium alloy had higher stable discharge voltage, larger discharge capacity and better discharging performance than AZ31 alloy.
