合金元素(Sn、Sb、Si、Mn)对Al-Ga-In-M合金阳极电化学性能影响
Effects of Alloy Elements(Sn,Sb,Si,Mn)on the Electrochemical Performance of Al-Ga-In-M Anode for the Seawater Oxygen-Dissolved Battery
摘要
Abstract
The Al-Ga-In-M quaternary aluminum alloy anode was obtained by modifying the Al-Ga-In aluminum alloy with alloy elements of Sn,Sb,Si and Mn.The properties of Al-Ga-In-M quaternary aluminum alloy were studied by X-ray diffraction(XRD),scanning electron microscope(SEM),electrochemical experiments,and battery discharge tests.The results show that Sn and Sb can improve the electrochemical activity of Al-Ga-In aluminum alloy.Furthermore,Sn displays the most significant increase for the aluminum anode based on the"dissolution and redeposition"mechanism,but serious local corrosion occurs,resulting in a high self-corrosion rate.On the other hand,Si and Mn reduce the electrochemical activity of Al-Ga-In aluminum alloy and show good self-corrosion resistance.When combining the anode with 20%Pt-C composite cathode,Al-Ga-In-Sn alloy has the highest discharge voltage(1.5 V at 0.5 mA/cm2 constant current density),Al-Ga-In-Si alloy anode exhibits excellent discharge capacity(2941 A·h/kg),and Al-Ga-In-Sb alloy anodes have the highest energy density(1447.4 Wh/kg).关键词
