摘要 研究了Al-0.5Mg-0.1Sn-0.1Si-0.02In合金作为铝空气电池的阳极材料,在2 mol/L Na Cl,4 mol/L Na OH乙醇-10%水,4 mol/L Na OH溶液中的腐蚀行为及电化学性能。结果表明,该合金在4 mol/L Na OH乙醇-10%水溶液中性能优良,具有较高的阳极利用率及较低的自腐蚀速率。腐蚀形貌及电化学阻抗谱测试结果与合金腐蚀特性一致。通过对比Zn在4 mol/L Na OH溶液中的电化学性能,Al-0.5Mg-0.1Sn-0.1Si-0.02In合金在4 mol/L Na OH乙醇-10%水介质中作为铝空气电池的阳极材料具有可行性。 As anode material for aluminum-air battery, Al-0.5Mg-0.1Sn-0.1Si-0.02In alloy was pre- pared, and then its corrosion behavior and electrochemical performance were investigated in sev- eral solutions such as 2 mol/L NaCl, 4 mol/L NaOH and 4 mol/L NaOH ethanol+10%water. The results show that the alloy exhibited the optimal electrochemical performance in 4 mol/L NaOH ethanol-10% water solutions i.e. the alloy has higher anodic utilization and lower free-corrosion rate. Results of SEM observation and EIS measurements of the alloy all coincide well with the above corrosion performance for the alloy. Therefore, the A1-0.5Mg-0.1Sn-0.1Si-0.02In alloy has good feasibility as anode material for aluminum-air battery in 4 mol/L NaOH ethanol+10% water solution.
