Abstract: A system for non-destructive determination of the degree of fluorination in carbon monofluoride (CFx) during the process of CFx synthesis is described. The system includes a measuring generator containing a capacitive sensor for measuring a respective capacitance, a base generator containing a capacitive sensor for measuring a base capacitance, and a processor for determining a difference between the respective capacitance and the base capacitance. The system is configured to determine the degree of fluorination based on the difference between the respective capacitance and the base capacitance.

Abstract: The present invention is a method and related automatic system for non-destructive determination of physical-chemical properties of powdered in particular as related to the quality control of powdered materials used in battery industry, for example determination of carbon monofluoride (CFx) degree of fluorination during the process of CFx synthesis.

Abstract: A method of producing high purity germanium tetrafluoride comprising the step of flowing a mixture of inert gas and fluorine gas through a reactor chamber preferably containing germanium powder. The reactor effluent stream is conducted through at least one product trap effective for condensing and retaining at least a portion of the germanium tetrafluoride product. The product is preferably then purified by repeatedly subliming the product as necessary to remove volatile impurities.

Abstract: A small, portable electrochemical power cell, having an output voltage of over 4 V, and preferably over 5 V, includes an anode, a cathode having a fluorine compound and an electrolyte having an organic sulfur-containing compound to maintain ionic conductivity between the anode and the cathode. A method of fabricating such an electrochemical power cell includes the step adding an electrolyte having an organic, sulfur-containing compound to maintain electrical conductivity between the anode and the cathode. An electrochemical power cell having a lithium anode, a CoF3 cathode, an electrolyte to maintain ionic conductivity between the anode and the cathode and a cobalt complexing material within the electrolyte to complex cobalt ions is described.

Abstract: Potassium tetrafluoroaluminate and potassium hexafluoroaluminate have been produced by three new processes: (a) by reacting alumina trihydrate with freshly produced, hot, solvated potassium fluoride or potassium bifluoride solution in presence of stoichiometric amounts and/or an excess of hydrogen fluoride, or (b) by reacting aluminum trifluoride trihydrate with hot aqueous solution in potassium fluoride or potassium bifluoride, or (c) by generating in situ potassium aluminate by reacting alumina trihydrate with hot aqueous potassium hydroxide and treating the same with aqueous or anhydrous hydrogen fluoride.
