Abstract: A battery electrode composition is provided comprising composite particles, with each composite particle comprising active material and a scaffolding matrix. The active material is provided to store and release ions during battery operation. For certain active materials of interest, the storing and releasing of the ions causes a substantial change in volume of the active material. The scaffolding matrix is provided as a porous, electrically-conductive scaffolding matrix within which the active material is disposed. In this way, the scaffolding matrix structurally supports the active material, electrically interconnects the active material, and accommodates the changes in volume of the active material.

Abstract: Batteries such as Li-ion batteries are provided that comprise anode and cathode electrodes, an electrolyte ionically coupling the anode and the cathode, and a separator electrically separating the anode and the cathode. In some designs, the electrolyte may comprise, for example, a mixture of (i) a Li-ion salt with (ii) at least one other metal salt having a metal with a standard reduction potential below −2.3 V vs. Standard Hydrogen Electrode (SHE). In other designs, the electrolyte may be disposed in conjunction with an electrolyte solvent that comprises, for example, about 10 to about 100 wt. % ether. In still other designs, the battery may further comprise anode and cathode interfacial layers (e.g., solid electrolyte interphase (SEI)) disposed between the respective electrode and the electrolyte and having different types of fragments of electrolyte solvent molecules as compared to each other.

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/cm2 and 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 fluoride material and a nanoporous, electrically-conductive scaffolding matrix within which the active fluoride material is disposed. The active fluoride material is provided to store and release ions during battery operation. The storing and releasing of the ions may cause a substantial change in volume of the active material. The scaffolding matrix structurally supports the active material, electrically interconnects the active material, and accommodates the changes in volume of the active material.

Abstract: A catalyst-free synthesis method for the formation of a metalorganic compound comprising a desired (first) metal may include, for example, selecting another (second) metal and an organic solvent, with the second metal being selected to (i) be more reactive with respect to the organic solvent than the first metal and (ii) form, upon exposure of the second metal to the organic solvent, a reaction by-product that is more soluble in the organic solvent than the metalorganic compound. An alloy comprising the first metal and the second metal may be first produced (e.g., formed or otherwise obtained) and then treated with the organic solvent in a liquid phase or a vapor phase to form a mixture comprising (i) the reaction by-product comprising the second metal and (ii) the metalorganic compound comprising the first metal. The metalorganic compound may then be separated from the mixture in the form of a solid.

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.

Abstract: A battery electrode composition is provided that comprises composite particles. Each of the composite particles in the composition (which may represent all or a portion of a larger composition) may comprise a porous electrode particle and a filler material. The porous electrode particle may comprise active material provided to store and release ions during battery operation. The filler material may occupy at least a portion of the pores of the electrode particle. The filler material may be liquid and not substantially conductive with respect to electron transport.
