Abstract: 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 β-position or does not possess a carbon in the β-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.

Abstract: Processes and reaction mixtures including non-aqueous solvent mixtures are presented. Non-aqueous solvent mixtures including fluoride salt and non-aqueous solvent combinations are provided that possess high fluoride ion concentrations useful for a range of applications, including organic synthesis. Further non-aqueous solvent mixtures are provided including a salt possessing a non-fluoride anion and a non-aqueous solvent that, when contacted with aqueous fluoride-containing reagents, extract fluoride ions to form non-aqueous fluoride-ion solutions possessing high fluoride-ion concentrations. The salts include an organic cation that does not possess a carbon in the β-position or does not possess a carbon in the β-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. The combination of 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.

Abstract: Provided herein is a class of copolymers, including triblock brush copolymers having specific block configurations, for example, ABC triblock brush copolymers and ABA triblock brush copolymers. In an embodiment, for example, copolymers of the invention incorporate various polymer side chain groups which contribute beneficial physical, chemical, or electronic properties such as increased mechanical or elastic strength, improved ionic or electric conductivity. In some embodiments, the provided copolymers exhibit advantageous steric properties allowing for rapid self-assembly into a variety of morphologies that are substantially different than non-brush, block copolymers.

Abstract: 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.

Abstract: 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.
