摘要:
本文制备了三种Al-Zn-In-Mg-Ga-Sn新型铝合金阳极，研究铝阳极在常温海水中的电化学性能和电流效率。结果表明：在工作电位下，当Ga元素的含量为0.03 wt%时，电荷转移电阻为4.344 Ω?cm2，电流效率为95.25 %。同时Ga元素含量的增加，使铝阳极开路电位负移，电流效率增加，有效抑制了钝化膜的产生。恒电流放电试验表明，Ga元素含量增加，铝阳极的放电激活时间变短，放电电位负移。
Abstract:
Three kinds of Al-Zn-In-Mg-Ga-Sn new aluminum alloys were prepared as the anodes of seawater batteries. The electrochemical behavior and current efficiency of the aluminum anodes in normal temperature seawater were studied. The results indicated that at the working potential, when the mass percentage content of Ga element was 0.03 %, the charge transfer resistance was 4.344 Ω?cm2, and the current efficiency was 95.25 %. The increase of the Ga element content caused the aluminum anode open circuit potential to shift negatively and the current efficiency to increase and effectively suppressed the generation of the passivation film. The galvanostatic discharge test showed that increasing the content of Ga element, the discharge activation time of the aluminum anode became shorter, and the discharge potential was negatively shifted.
