Abstract

The invention belongs to the field of metal materials and particularly relates to an anode material for an air battery and a preparation method of the anode material. The alloy material is negative in open-circuit voltage and low in self-corrosion rate. The invention also provides the preparation method of the anode material for the air battery. The preparation method is simple in process and low in production cost, and is suitable for industrial production. The anode material comprises the following components in percent by weight: 0.5-0.8% of Zr, 0.01-0.04% of Sm, 0.5-0.7% of Cd, 0.5-0.7% of Be, 0.05-0.07% of Fe, 0.04-0.06% of Os, 6-9% of Zn and the balance of Mg.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to an anode material for an air battery and a preparation method thereof. Background technique [0002] The CN201210281070.X invention discloses a manganese-containing aluminum alloy anode material for an air battery and its preparation method and application. The air battery includes a manganese-containing aluminum alloy anode, an air cathode and a neutral electrolyte. The anode material is composed of the following elements by weight: Mg: 0.05~2.5%; Sn: 0.05~1.5%; Ga: 0.05~2.5%; Mn: 0.1~1%; the balance is Al, and the inert gas protection induction melting method is used preparation. The presence of alumina in Al-based alloys results in low self-corrosion rates. Contents of the invention [0003] The purpose of the present invention is to provide an anode material for an air battery, which has a negative open circuit voltage and a low self-corrosion rate, aiming at th...
