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.
Key words: seawater battery; magnesium anode; activation; corrosion; alloying element; second phase
