摘    要:镁阳极材料具有电负性好,比能量高以及密度小等优异性能,在海水电池领域具有广阔的应用前景。综述了近年来国内外镁阳极海水电池的研究及应用,讨论镁阳极材料的活化机制和腐蚀行为,探讨合金元素和第二相对镁阳极电化学活性和耐腐蚀性能的影响,指出今后海水电池用镁阳极材料的发展应在充分研究合金元素活化机理和第二相影响的基础上,研制出自腐蚀速率更小、阳极利用率更高以及比能量更大的新型镁合金阳极材料。

Abstract: The magnesium anodes have great development in seawater battery due to their excellent properties, such as good electro negativity, high specific capacity and low density. The researches and applications of magnesium anodes in seawater battery in recent years were reviewed. The influences of activation mechanism, corrosion behavior, alloying elements and second phases on the electrochemical and corrosion properties of magnesium anodes were discussed. It is indicated that the development of magnesium anodes in seawater battery is to prepare novel anode materials with less self-corrosion, higher anode utilization ratio and larger specific energy based on studying activation mechanism of alloying elements and second phases.
