In　this　work,　the　combined　effects　of　heat　treatment　and　Sb　addition　on　the　discharge　performance　of　Al-Sb　alloys　as　anode　for　Al-air　batteries　have　been　evaluated　experimentally.　The　results　indicate　that　heat　treatment　decreases　the　electrochemical　and　discharge　activities　of　Al-Sb　alloys.　Heat-treated　Al-Sb　alloys　at　550　degrees　C　for　3　h　show　an　improved　anode　performance.　The　Al-0.02Sb　alloy　exhibits　a　high　discharge　capacity　and　anodic　efficiency　of　2758　Ah　kg(-1)　and　92.6%,　respectively.　Further　prolonging　the　heat　treatment　time　results　in　a　decrease　in　anode　performance.　Microstructure　characterization　indicates　that　such　negative　effect　is　due　to　the　higher-temperature　and　prolonged　heat　treatment　to　bring　out　significant　grain　growth　and　coarsening　of　Al-Sb　precipitates.　The　corresponding　corrosion　behaviors　are　also　discussed　in　detail.
