Abstract
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.
