    摘要: Carbon fluoride is synthesized by reactively or high intensity/energy milling at ambient room temperature carbon-containing material (such as graphite, carbon black, coke, or other carbon-based material) with an inorganic fluoride agent (such as cobalt trifluoride) other than fluorine gas. The following chemical reaction occurs: xC+CoF3→CxF+CoF2, wherein x equals 1 to 4. The CxF is separated from the CoF2 and the CoF3 by digesting the CxF, CoF2 and the CoF3 in hot water of at least approximately 90° C. causing the CoF2 to dissolve; and then filtering the CoF2. The CoF3 is unreacted and undergoes hydrolysis in the hot water to form Co(OH)3 or Co2O3.3H2O, which is removed by washing with sulfuric acid. Alternatively, the CxF is separated from the CoF2 and the CoF3 by digesting the CxF, CoF2 and the CoF3 in heated sulfuric acid followed by filtration and washing with sulfuric acid and then with hot water. The synthesized carbon fluoride is used to form a cathode in electrochemical cells, such as lithium batteries.

    摘要: An electrolyte for a metal-oxygen battery includes a non-aqueous solvent which is characterized in that the solubility of oxygen therein is at least 0.1150 cc O2/cc of solvent at STP. The electrolyte also includes an electrolyte salt dissolved in the solvent. The solvent may comprise a mixture of materials in which at least 50%, on a weight basis, of the materials have an oxygen solubility of at least 0.1760 cc O2/cc at STP. Also disclosed is a method for optimizing the composition of an electrolyte for a metal-oxygen battery by selecting the solvent for the electrolyte from those materials which will dissolve the electrolyte salt and which have a solubility for oxygen which is at least 0.1150 cc O2/cc at STP.

    摘要: A catalyst composition for use in a rechargeable metal-air electrochemical cell comprises an oxygen evolution catalyst coated with a thin film deposition of a binder and an electrically conductive particulate material which is not corroded during charge. This catalyst is useful to make an air electrode which has greater corrosion protection than an air electrode having an oxygen evolution catalyst without the thin film deposition.
