  • Publication number: 20240086563
    Abstract: A method for operating a graph database, including receiving, by a computer system, a query to a particular graph database, the query identifying a plurality of vertices of the particular graph database. The method further includes performing, by the computer system, hash operations on two or more of the plurality of vertices to generate respective hash values and dividing, using the respective hash values, the query into a plurality of sub-queries, each corresponding to a subset of the plurality of vertices. The method also includes sending, by the computer system, ones of the plurality of sub-queries to a plurality of database repositories for the particular graph database.

  • Patent number: 6187479
    Abstract: A rechargeable battery or cell is disclosed in which the electrode active material consists of at least one nonmetallic compound or salt of the electropositive species on which the cell is based, and the electrolyte or electrolyte solvent consists predominantly of a halogen-bearing or chalcogen-bearing covalent compound such as SOCl2 or SO2Cl2. Also disclosed are cell component materials which include electrodes that consist primarily of salts of the cell electropositive species and chemically compatible electrolytes. These latter electrolytes include several newly discovered ambient temperature molten salt systems based on the AlCl3—PCl5 binary and the AlCl3—PCl5—PCl3 ternaries.

  • Patent number: 5786110
    Abstract: High-conductivity alkali-metal-ion containing electrolytes comprising viscous liquid or rubbery solid alkali metal salts which obtain conductivity by the domainate motion of cation ions which, when produced in accordance herewith, remain freely mobile at low temperatures. One embodiment relates to molten alkali metal salt electrolytes comprised of one or more alkali metal salt compositions which are substantially non-crystalline and have glass transition temperatures below room temperature.

  • Patent number: 5506073
    Abstract: A liquid, predominantly lithium-conducting, ionic electrolyte having exceptionally high conductivity at temperatures of 100.degree. C. or lower, including room temperature, and comprising the lithium salts selected from the group consisting of the thiocyanate, iodide, bromide, chloride, perchlorate, acetate, tetrafluoroborate, perfluoromethane sulfonate, perfluoromethane sulfonamide, tetrahaloaluminate, and heptahaloaluminate salts of lithium, with or without a magnesium-salt selected from the group consisting of the perchlorate and acetate salts of magnesium. Certain of the latter embodiments may also contain molecular additives from the group of acetonitrile (CH.sub.3 CN) succinnonitrile (CH.sub.2 CN).sub.2, and tetraglyme (CH.sub.3 --O--CH.sub.2 --CH.sub.2 --O--).sub.2 (or like solvents) solvated to a Mg.sup.+2 cation to lower the freezing point of the electrolyte below room temperature.

  • Patent number: 5484670
    Abstract: A liquid, predominantly lithium-conducting, ionic electrolyte is described which has exceptionally high conductivity at temperatures of 100.degree. C. or lower, including room temperature. It comprises molten lithium salts or salt mixtures in which a small amount of an anionic polymer lithium salt is dissolved to stabilize the liquid against recrystallization. Further, a liquid ionic electrolyte which has been rubberized by addition of an extra proportion of anionic polymer, and which has good chemical and electrochemical stability, is described. This presents an attractive alternative to conventional salt-in-polymer electrolytes which are not cationic conductors.
