Metallic negative electrode materials for nonaqueous lithium-ion batteries were prepared, characterized, and demonstrated. The materials with the best electrical performance are nickel-tin alloys, have small particle size, and can incorporate up to 550 mAh/g of lithium. These materials offer specific capacity, capacity density, and reversibility comparable to tin oxides without the high irreversible capacity that has precluded tin oxide commercialization. When cycled calvanostatically, the nickel-tin alloy offer low capacity fade while reversibly incorporating lithium up to 327 mAh/g or 2,740 mAh/mL, over four times the capacity density typical for current carbonaceous Li-ion negative electrode materials. The irreversible capacity associated with these materials is 26%, or 76 mAh/g, when utilized at 300 mAh/g. When utilized in prototype Li-ion cells vs. either a LiNi{sub 1{minus}x}Co{sub x}O{sub 2} or LiMn{sub 2}O{sub 4} cathode material, low capacity fade was demonstrated while the metallic negative electrode material was utilized at 1500 mAh/mL.
