Embodiment 1
[0029] The battery material with high anode utilization rate of the present invention, the weight percentage of each component is: Si 0.1%, Pr 0.01%, Ba 0.01%, Fe 0.02%, Li 0.01%, Os 0.01%, Cu 0.5%, Al 4%, The remainder is Mg.
[0030] The preparation method of the high anode utilization rate battery material of the present invention comprises the following steps:
[0031] 1) First, the ingredients are prepared according to the above ingredients. The raw materials Si, Pr, Ba, Fe, Li, Os, Cu, Al, Mg are added in the form of pure substances, and the purity is greater than 99.9%;
[0032] 2) Use a crucible resistance furnace to smelt the alloy raw material. First heat the crucible to 400°C, and then evenly sprinkle magnesium flux accounting for 2% of the weight of the alloy raw material on the crucible wall and bottom; then put the alloy raw material into the crucible, and then put the alloy Sprinkle magnesium flux accounting for 1% of the weight of the alloy raw material on the...
