The new aluminum alloys anode materials of fine electrochemistry active in the alkaline battery have been studied. The material of aluminum alloy has been made by the method of molten and the pressure processing technology; The electrochemistry performance of the Al alloy anode material has been studied by electrochemical methods. The self-corrosion rat of Al alloy anode has been studied by methods of immersed in aqueous medium .The results show that the electrode voltage of the Al alloy anode in medium of 3.5%NaCl、3.5%NaCl and25%NaOH is very negative and the self-corrosion rat is very small. The voltage of Al/AgO battery is 1.62V, the self-corrosion rat of Al/AgO battery is 21ml/(cm^2·min). The new aluminum alloys anode materials would be used to develop aluminum alloy battery with high energy density.
