Performance of Mg-Zn-Cu Series Alloy as Anodic Material for Magnesium Battery

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.
