摘要

Mg-6Al-7Pb (wt.%) alloys with different Ce contents are prepared and their electrochemical dischargeperformances are measured in this research. Under casting condition, Mg-6Al-7Pb-0.3Ce alloy showsbetter electrochemical activity than other alloys. Subsequently, the discharge property of Mg-6Al-7Pb-0.3Ce alloy is further enhanced by multi-pass hot rolling. The result is verified by electrochemical testsand morphology observation. Mg2Pb and Al4Ce phases are observed, and fine grains are obtained inas-rolled Mg-6Al-7Pb-0.3Ce alloy. For as-rolled Mg-6Al-7Pb-0.3Ce alloy, the increased dischargeperformance is attributed to the synergistic effect of the dispersive Al4Ce and Mg2Pb phases. The Mgair battery based on as-rolled Mg-6Al-7Pb-0.3Ce alloy supplies higher peak power density (102.7mW·cm-2) than that based on as-rolled Mg-6Al-7Pb anode. Therefore, the as-rolled Mg-6Al-7Pb-0.3Ce alloy is an excellent anode material for Mg-air battery.
