Abstract

The invention belongs to the field of metal materials and relates to an electrode material containing rare earth and magnesium as well as a preparation method for the electrode material. The open-circuit voltage of the alloy material of the electrode material containing rare earth and magnesium is a negative value and the absolute value of the negative value is relatively large. The invention further provides the preparation method for the electrode material. The preparation method is simple in process, low in production cost and suitable for industrial production. The electrode material comprises the following components in percentage by weight: 0.5-0.8% of Sr, 0.03-0.06% of Y, 0.4-0.7% of Sb, 0.5-0.8% of Fe, 1-4% of Ni, 0.07-0.09% of Os and the balancing amount of Mg.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a rare earth magnesium electrode material and a preparation method. Background technique [0002] CN201010124355.3 discloses an electrode material, with aluminum as the matrix, containing 0.01-1.0wt% of activated element mercury, 0.05-2.0wt% of gallium, 0.05-2.0wt% of magnesium, 0.01-1.0wt% of tin and 0.01-1.0 wt% zinc. The invention optimizes the alloy elements and components that can reduce the passivation and polarization of aluminum anode materials and improve the electrochemical activity and corrosion resistance of aluminum anode materials through the study of alloy composition design, electrochemical performance and element activation mechanism of aluminum anode materials. , has prepared a high-power seawater activated power battery aluminum anode material with the advantages of short activation time, high current efficiency, stable discharge, less hydrogen evolu...
