The present disclosure relates to fluoride ion batteries and structures of metal based electrode materials for various fluoride ion batteries. The structures of the metal based electrode materials comprise one or more shells or interfaces, enabling the electrodes to operate at room temperature with a liquid electrolyte.

Liquid-type room-temperature fluoride ion batteries

The present disclosure relates to a method of making core-shell and yolk-shell nanoparticles, and to electrodes comprising the same. The core-shell and yolk-shell nanoparticles and electrodes comprising them are suitable for use in electrochemical cells, such as fluoride shuttle batteries. The shell may protect the metal core from oxidation, including in an electrochemical cell. In some embodiments, an electrochemically active structure includes a dimensionally changeable active material forming a particle that expands or contracts upon reaction with or release of fluoride ions. One or more particles are at least partially surrounded with a fluoride-conducting encapsulant and optionally one or more voids are formed between the active material and the encapsulant using sacrificial layers or selective etching. The fluoride-conducting encapsulant may comprise one or more metals. When the electrochemically active structures are used in secondary batteries, the presence of voids can accommodate dimensional changes of the active material.

Barium-doped composite electrode materials for fluoride-ion electrochemical cells

An electrochemically active structure having a core and a shell at least partially surrounding the core. Also a method of making the electrochemically active structure as described herein as well as electrochemical cells comprising the electrochemically active structure as described herein.

Electroactive materials modified with molecular thin film shell

The present disclosure relates to a method of making core-shell and yolk-shell nanoparticles, and to electrodes comprising the same. The core-shell and yolk-shell nanoparticles and electrodes comprising them are suitable for use in electrochemical cells, such as fluoride shuttle batteries. The shell may protect the metal core from oxidation, including in an electrochemical cell. In some embodiments, an electrochemically active structure includes a dimensionally changeable active material forming a particle that expands or contracts upon reaction with or release of fluoride ions. One or more particles are at least partially surrounded with a fluoride-conducting encapsulant and optionally one or more voids are formed between the active material and the encapsulant using sacrificial layers or selective etching. When the electrochemically active structures are used in secondary batteries, the presence of voids can accommodate dimensional changes of the active material.

Composite electrode materials for fluoride-ion electrochemical cells

Electrolyte solutions including at least one anhydrous fluoride salt and at least one non-aqueous solvent are presented. The fluoride salt includes an organic cation having a charge center (e.g., N, P, S, or O) that does not possess a carbon in the &#x3b2;-position or does not possess a carbon in the &#x3b2;-position having a bound hydrogen. This salt structure facilitates its ability to be made anhydrous without decomposition. Example anhydrous fluoride salts include (2,2-dimethylpropyl)trimethylammonium fluoride and bis(2,2-dimethylpropyl)dimethylammonium fluoride. Combining these fluoride salts with at least one fluorine-containing non-aqueous solvent (e.g., bis(2,2,2-trifluoroethyl)ether; (BTFE)) promotes solubility of the salt within the non-aqueous solvents. The solvent may be a mixture of at least one non-aqueous, fluorine-containing solvent and at least one other non-aqueous, fluorine or non-fluorine containing solvent (e.g., BTFE and propionitrile or dimethoxyethane). The electrolyte solutions may be employed in electrochemical cells, such as batteries, fuel cells, electrolysis systems, and capacitors.

Non-aqueous fluoride salts, solutions, and their uses

The present disclosure relates to an electrochemical cell which may be used, for example, in a rechargeable battery based on the reversible transfer of halide anions, and a method for making an electrolyte composition for use in the same. The electrochemical cell includes a positive electrode, a negative electrode, and an electrolyte composition positioned between the two electrodes, where the electrolyte composition contains a crown ether-metal halide complex in a solvent.

Liquid electrolyte for battery

A fluoride shuttle (F-shuttle) battery and nanostructures of copper based cathode materials in the fluoride shuttle battery. The F-shuttle batteries include a liquid electrolyte, which allows the F-shuttle batteries to operate under room temperature. The minimum thickness of copper layer within the copper nanostructures is no more than 20 nm. The thickness of copper layer within the copper nanostructures is controlled and reduced to ensure the energy densities of F-shuttle batteries.

Nanostructural designs for electrode materials of fluoride ion batteries

An anode for a fluoride ion electrochemical cell is provided and includes a layered material of hard carbon, nitrogen doped graphite, boron doped graphite, TiS, MoS, TiSe, MoSe, VS, VSe, electrides of alkali earth metal nitrides, electrides of metal carbides, or combinations thereof. The anode may be included in a fluoride ion electrochemical cell, which additionally includes a cathode and a fluoride ion electrolyte arranged between the cathode and the anode. At least one of the cathode and the anode reversibly exchange the fluoride ions with the electrolyte during charging or discharging of the electrochemical cell.

Anode for fluoride ion battery

The invention generally relates to electrochemically active structures and methods of making thereof. More specifically, the invention relates to electrochemically active structure comprising a crystalline electride comprising a nitride or carbide of at least one of: an alkaline earth metal, a transition metal, a lanthanide metal, or a combination thereof, wherein the electride has a lattice capable of intercalating at least one ion, thereby releasing at least one electron into an external circuit; and wherein a change in lattice volume of the electride upon intercalating the at least one ion is less than about 40%. Further, methods of making these electrochemically active structures are disclosed. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
