Abstract Serious self‐corrosion and passivation film of Al‐air battery reduces the actual energy density limits its commercial application. The corrosion inhibition effect l ‐cysteine on low‐cost Al anode alloy was studied using hydrogen evolution electrochemical tests. results show that can significantly reduce current electrode in 4 M KOH improve activity electrode. optimum amount inhibitor (0.5 M) improved performance battery. utilization efficiency reached 82.73%, life prolonged by nearly three times. cell capacity, energy, maximum power increased from 1990.67 mAh·g −1 , 1672.16 Wh·kg 34.62 mW·cm −2 system without to 2465.33 2144.84 64.4 with 0.5 ‐cysteine. researchers also used X‐ray photoelectron spectroscopy (XPS) other techniques combined quantum chemistry calculation obtain ─COOH, ─NH 2 ─SH form physical adsorption films surface, which improves resistance anode.
