Abstract: An aspect is directed to a Li-ion battery, comprising anode and cathode electrode, an electrolyte ionically coupling the anode and the cathode electrodes, and a separator electrically separating the anode and the cathode electrodes, wherein the anode electrode comprises a mixture of conversion-type anode material and intercalation-type anode material, wherein the conversion-type anode material exhibits median specific reversible capacity in the range from about 1400 mAh/g to about 2200 mAh/g, and wherein the conversion-type anode material exhibits first cycle coulombic efficiency in the range from about 88% to about 96%.

Abstract: A battery electrode composition is provided that comprises composite particles. Each composite particle may comprise, for example, active lithium fluoride/metal nanocomposite material optionally embedded into a nanoporous, electrically-conductive skeleton matrix material particle(s), where each of these composite particles is further encased in a Li-ion permeable, chemically and mechanically robust, protective outer shell that is impermeable to electrolyte solvent molecules. The active lithium fluoride/metal nanocomposite material is provided to store and release Li ions during battery operation.
