  • Safe Battery Solvents
    Publication number: 20160294013
    Abstract: An ion transporting solvent for use with batteries can be improved by simultaneously shortening a phosphazene compound's pendent groups, eliminating most or all of the distal ion carriers, and randomizing the solvent molecules so as to intentionally disrupt symmetry to the maximum degree possible. The combination of these strategies dramatically improves battery performance to the point where the performance recorded is comparable to batteries using conventional organic solvents.

  • Process for modifying the rheology of polyolefins
    Patent number: 6077914
    Abstract: The molecular weight of a polyolefin such as polypropylene is reduced, as evidenced by lowered viscosity and increased melt flow rate, by treatment with an inorganic peroxygen selected from metal persulfates, ammonium persulfates, and any mixtures thereof. The treatment avoids or minimizes the color or odor attendant treatment with organic peroxygens and the toxic products of organic persulfate decomposition, and avoids the special handling required with organic peroxides.

  • Recovery of lithium values from brines
    Patent number: 5389349
    Abstract: Morphologically altered pellets of a polycrystalline hydrated alumina, intercalated with LiX (where LiX is a lithium salt, preferably LiCl), is prepared by contacting the polycrystalline structure with LiX solution carried in NaCl brine, the LiX creating lithium-specific sites of intercalation in the crystalline structure, and the material is used in a LiX absorption process involving unloading LiX from the pellets, and then passing a LiX-containing brine through the pellets to capture more LiX in the Li-depleted active sites, and repeating the unloading and loading of the LiX a plurality of cycles. The unloaded LiX is collected as crude product which can be concentrated by evaporation and removing precipitated NaCl.
