The present disclosure provides a process for producing trifluoroiodomethane (CFI). The process includes providing vapor-phase reactants including trifluoroacetyl halide, hydrogen, and iodine, heating the vapor-phase reactants, and reacting the heated vapor-phase reactants in the presence of a catalyst to produce trifluoroiodomethane. The catalyst includes a transition metal.

The present disclosure provides a method for purifying trifluoroiodomethane. The method includes providing a process stream comprising trifluoroiodomethane, organic impurities, and acid impurities; reacting the process stream with a basic aqueous solution, the basic aqueous solution comprising water and at least one base selected from the group of an alkali metal carbonate and an alkali metal hydroxide; and separating at least some of the organic impurities from the process stream.

Disclosed are copolymers and terpolymers chlorotrifluoroethylene and vinyl chloride having improved properties, and particularly a high glass transition temperature, for use in membranes, coatings, barrier films, and other applications and process for forming such copolymers and terpolymers, which are useful in reverse osmosis desalination, nanofiltration, ultrafiltration, microfiltration, membrane distillation, pervaporation, selective gas separation, batteries and fuel cells.

Copolymers and terpolymers based on chlorotrifluoroethylene and vinyl chloride and uses thereof

Non-aqueous electrolyte solutions capable of protecting negative electrode materials such as lithium metal and carbonaceous materials in energy storage electrochemical cells (e.g., lithium metal batteries, lithium ion batteries and supercapacitors) include an electrolyte salt, a non-aqueous electrolyte solvent mixture, an unsaturated organic compound 4-methylene-1,3-dioxolan-2-one or 4,5-dimethylene-1,3-dioxolan-2-one, and other optional additives. The 1,3-dioxolan-2-ones help to form a good solid electrolyte interface on the negative electrode surface.

Nitrogen silylated compounds are useful as additives in a nonaqueous electrolytic solution. The electrolytic solution including such additives is suitable for use in electrochemical cells such as lithium and lithium ion batteries. Batteries using this electrolytic solution have long cycle life and high capacity retention.

Nitrogen silylated compounds as additives in non-aqueous solutions for electrochemical cells

A process is provided to produce non-aqueous electrolytic solution for use in batteries having low acid content and low water content. The invention involves removing acids and water from non-aqueous electrolytic solutions typically found in lithium or lithium-ion batteries by using nitrogen-containing compounds such as triazines. After treatment by a triazine such as melamine, the concentrations of acids and water in the electrolytic solutions are substantially decreased. The present invention provides a process to prepare extremely pure electrolytic solutions having low (&#x3c;20 ppm) concentrations of both water and acids.

The invention relates to the use of an amine oxide as an additive in a nonaqueous electrolytic solution. The electrolytic solution is suitable for use in electrochemical cells such as lithium batteries and lithium ion batteries. Batteries using this electrolyte solution have long life and high capacity retention.

Nonaqueous electrolytic solution for electrochemical cells

The invention relates to the use of aromatic phosphite compounds as stabilizers for nonaqueous electrolytic solutions containing halogenated salts such as LiPFand LiBF. The electrolyte containing such a phosphite exhibits excellent shelf life storage at ambient and high temperatures. The electrolytic solution is suitable for use in electrochemical cells such as lithium (ion) rechargeable batteries and supercapacitors.

Stabilized nonaqueous electrolytes for rechargeable batteries

The present invention provides BZPA products with improved flowability and two methods of producing such BZPA products. Both methods successfully produce BZPA products that are not prone to agglomerate upon storage, and thus the flowability of such BZPA products does not degrade over time. The first method includes mechanically forming the BZPA crystals into large compacted pellets or briquettes without the introduction of any additives or binders. The compacted pellets are large enough that the physical and chemical effects that occur on the surface of small crystal particles are eliminated or minimized, but small enough that the BZPA can be easily handled and used in commercial applications. The second method includes adding a substantially inert anti-caking agent to the BZPA crystals to minimize or retard their tendency to agglomerate. The preferred anti-caking agent is silicon dioxide (SiO), which is blended with the BZPA crystals in small amounts.
