Abstract:

An anode material composition is provided for a metal-ion battery that comprises an active material coating, a current conductive current collector, and a conductive interlayer coupling the active material coating to the current collector. The active material coating may have a capacity loading of at least 2 mAh/cmand comprise active material particles that exhibit volume expansion in the range of about 8 vol. % to about 160 vol. % during a first charge-discharge cycle and volume expansion in the range of about 4 vol. % to about 50 vol. % during one or more subsequent charge-discharge cycles.

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.

H01M 4/13

Abstract:

Battery electrode compositions and methods of fabrication are provided that utilize composite particles. Each of the composite particles may comprise, for example, a high-capacity active material and a porous, electrically-conductive scaffolding matrix material. The active material may store and release ions during battery operation, and may exhibit (i) a specific capacity of at least 220 mAh/g as a cathode active material or (ii) a specific capacity of at least 400 mAh/g as an anode active material. The active material may be disposed in the pores of the scaffolding matrix material. According to various designs, each composite particle may exhibit at least one material property that changes from the center to the perimeter of the scaffolding matrix material.
