| dc.description.abstract | 本研究主要透過合金改質的方式，藉由微結構與電化學性質分析，探討不同銦含量(0.1、0.2、0.3wt%)對Al-5Zn-0.1Sn陽極合金電化學之影響。結果顯示，隨著In含量增加，在晶界處的鏈狀In-Sn相(活化點)隨之提升，使其抑制晶粒成長，造成晶界總表面積增加。在腐蝕過程中，能呈現更均勻的腐蝕並提升合金活性。結合極化曲線(LSV)、交流阻抗(EIS)及析氫腐蝕試驗(HER)，從中觀察鋁陽極合金的活化機制。
再將改質鋁合金應用於空氣電池陽極進行放電檢測，相較於未添加In(Al-5Zn-0.1Sn)合金，Al-5Zn-0.1Sn-0.1In 陽極效率提升8%，Al-5Zn-0.1Sn-0.3In能量密度提升35%。綜上所述，Al-5Zn-0.1Sn-0.1In擁有最高的陽極效能，但其活性低於Al-5Zn-0.1Sn-0.3In，綜合評估下，Al-5Zn-0.1Sn-0.3In擁有最佳的能量密度。 | zh_TW |
| dc.description.abstract | This study primarily explores the electrochemical effects of different indium contents (0.1, 0.2, 0.3 wt%) on Al-5Zn-0.1Sn anode alloy through alloy modification, microstructure, and electrochemical property analysis. The results indicate that with the increase in In content, the chain-like In-Sn phase (activation points) at the grain boundaries increases, inhibiting grain growth and resulting in an increase in the total surface area of the grain boundaries. During the corrosion process, this leads to a more uniform corrosion and enhances the alloy′s activity. By combining polarization curves (LSV), electrochemical impedance spectroscopy (EIS), and hydrogen evolution corrosion tests (HER), the activation mechanism of the aluminum anode alloy was observed.
Furthermore, when the modified aluminum alloy is applied to the anode of an air battery for discharge testing, the Al-5Zn-0.1Sn-0.1In anode shows an 8% improvement in performance compared to the alloy without added indium(Al-5Zn-0.1Sn), and the Al-5Zn-0.1Sn-0.3In shows a 35% increase in energy density. In summary, the Al-5Zn-0.1Sn-0.1In alloy has the highest anode performance, but its activity is lower than that of Al-5Zn-0.1Sn-0.3In. Considering overall evaluations, the Al-5Zn-0.1Sn-0.3In alloy possesses the best energy density. | en_US |
