Novel Mg alloy anodes with high efficiency have great potential in seawater batteries for marine explorations. This work investigated the effect of indium addition and equal-channel angular pressing on discharge performance and electrochemical properties of commercial AZ61 alloy via hydrogen evolution, weight-loss test, electrochemical and discharge measurements in 3.5 wt% NaCl. The results indicated that indium addition promoted the formation of second phases due to the segregation effect. The pressing process effectively refined the grains and contributed to the uniform grain distribution, which was beneficial to the discharge performance and corrosion resistance of the Mg anodes. The pressed AZ61-In exhibited improved discharge activity and anode utilization compared to as-cast AZ61 and AZ61-In alloys.
