    摘要： An anode material for use in lithium based electrical cells is described. The anode material comprises a fine and uniform dispersion of second phase particles in lithium. The particles have an average particle size from about 0.5 .mu.M to about 40 .mu.M and are present at a concentration ranging from about 0.1 At % to about 10 At %. The anode material exhibits a reduction in dentrite and mossy Li formation, while maintaining the necessary mechanical properties of the material for easy working. The new anode demonstrates excellent cell performance and thermal stability.

    摘要： An aluminum film is formed on the surface of a substrate magnesium or magnesium alloy, and the resulting product is heated in a non-oxidizing or reducing gas having a high hydrostatic pressure at a temperature ranging from the eutectic point of the magnesium or magnesium alloy and the different metal to a temperature at or below which neither of the magnesium or magnesium alloy and the different metal is molten. This treatment provides a boundary layer between the aluminum film and the magnesium or magnesium alloy. This boundary layer is free from pinholes running from the interface of the aluminum film and the boundary layer to the magnesium or magnesium alloy ground. This surface-treated magnesium or magnesium alloy has excellent corrosion resistance surface electric conductivity, thermal conductivity and heat shock resistance.
