The invention relates to an anode material for an alkaline aluminum-air battery and a preparation method of the anode material, and belongs to the field of air batteries. The preparation method of theanode material for the alkaline aluminum-air battery is characterized in that the anode material is aluminum alloy, and the aluminum alloy consists of the following components in percentages by mass:0.05-0.20wt% of Sn, 0.05-0.15wt% of Ga, 0.2-1.0wt% of Mg, 0.1-0.5wt% of Mn, 0.1-0.3wt% of Zr, less than or equal to 0.30wt% of impurities and the balance of Al. The anode material is produced by a continuous cast rolling method, a production process is simple, the anode material is suitable for being produced in batches, defects of the anode material are reduced, the yield is increased, energy consumption is reduced, the production cost is lowered, and the economic benefit is good.

Description

technical field [0001] The invention relates to an anode material for an alkaline aluminum-air battery and a preparation method thereof, belonging to the field of air batteries. Background technique [0002] Due to the depletion of fossil fuels such as coal and oil, the increase in global energy demand, and the environmental pollution caused by the use of fossil fuels, human beings urgently need new energy sources to meet human production and life. Metal-air batteries have the characteristics of high efficiency and cleanliness, and have been mentioned as new energy storage devices. A metal-air battery is a metal fuel cell that uses a metal as the anode, oxygen in the air as the cathode, and uses a neutral or alkaline electrolyte as a medium to generate electricity through a chemical reaction under the action of a catalyst. [0003] At present, metal-air batteries that have been studied more include lithium-air batteries, aluminum-air batteries, zinc-air batteries, and magne...
