摘要（英）：

The invention discloses an aluminum alloy anode material for an air cell, a preparation method and an aluminum air cell. The aluminum alloy anode material is composed of the following ingredients, by weight, 0.05%-6% of Zn, 0.05%-4% of Ga and 0.01%-2% of In, the balance being Al. Zn, Ga and In elements are added in the aluminum alloy anode material, the electrochemical activity is good, the self-corrosion rate is low, the open circuit potential is less than and equal to -1.76V (vs.SHE) in an alkaline electrolyte, and an electromotive force of a monomer cell is more than 1.84V. Through alloying, the electrochemical performance of the anode is raised obviously, the self-corrosion rate is lowered, the self-corrosion rate is less than 5.12mg/(cm<2>*h), and surface corrosion is uniform. The aluminum alloy anode material has excellent performances, and is a novel aluminum alloy anode material suitable for usage in an alkaline electrolyte.
