Abstract: An electrode composition that includes an electrode material consisting essentially of at least one electrochemically inactive elemental metal and at least one electrochemically active elemental metal in the form of an amorphous mixture at ambient temperature. The mixture remains amorphous when the electrode composition is incorporated into a lithium battery and cycled through at least one full charge-discharge cycle at ambient temperature.

Abstract: An electrode composition for a lithium ion battery comprising particles having a single chemical composition. The particles consist of (a) at least one metal element selected from the group consisting of tin, aluminum, silicon, antimony, lead, germanium, magnesium, zinc, cadmium, bismuth, and indium; (b) at least one metal element selected from the group consisting of manganese, molybdenum, niobium, tungsten, tantalum, iron, copper, titanium, vanadium, chromium, nickel, cobalt, zirconium, tantalum, scandium, yttrium, ruthenium, platinum, and rhenium; and, optionally, (c) carbon, and have a microstructure characterized by a plurality of electrochemically inactive, nanometer-sized crystalline grains separated by electrochemically active non-crystalline regions.
