High　performance　of　Al　anode　for　Al-air　battery　was　achieved　via　coordinating　minor　In　and　Sb　additions　with　discharge　parameters.　The　electrochemical　behaviors,　discharge　performance　and　surface　structures　of　aluminum　electrodes　are　systematically　investigated　to　understand　the　alloying　chemistry　coordination　of　indium　and　antimony.　The　results　show　that　coordinating　indium　and　antimony　can　significantly　activate　the　Al　electrode　without　aggravating　the　hydrogen　evolution.　The　assembled　Al-air　cell　with　Al-0.05In-0.05Sb　electrode　exhibits　a　desirable　specific　capacity　and　energy　density　of　2638　Ah·kg−1　and　3166　Wh·kg−1,　respectively.　Furthermore,　antimony　has　better　activating　effect　than　indium,　especially　at　discharge　current　density　over　40　mA·cm−2.　The　activating　mechanisms　are　discussed　in　detail.　©　2024　Elsevier　Ltd
