Effects of hot rolling on the electrochemical behaviors and discharge performance of AZ61-In anodes for seawater activated batteries

In this research, corrosion behavior and discharge capabilities of the AZ61-In alloy experiencing hot rolling process have been discussed in detail. The results reveal that the introduction of indium to magnesium facilitates the dissolution of magnesium by augmenting a quantity of secondary phases, generating less-protective products. The corrosion resistance of AZI plus 50 % rolling reduction is improved attributed to the preferred basal orientation and further recrystallization. Moreover, the average discharge potentials of AZI-50 % can respec-tively reach-1.551 V and-1.234 V at 10 mA cm-2 and 50 mA cm-2, showing potential for application in seawater activated batteries.
