  • Publication number: 20090269676
    Abstract: A non-aqueous electrolyte for an electric current producing electrochemical cell is provided comprising an ionically conductive salt and an additional ionically conducting salt in a non-aqueous medium, the additional ionically conducting salt corresponding to the formula M+(Z*(J*)j)?, wherein: M is a lithium atom, Z* is an anion group containing two or more Lewis basic sites and comprising less than 50 atoms not including hydrogen atoms, J* independently each occurrence is a Lewis acid coordinated to at least one Lewis basic site of Z*, and optionally two or more such J* groups may be joined together in a moiety having multiple Lewis acidic functionality, and j is an integer from 2 to 12. The addition of these ionically conducting salts to electrolyte solutions containing LiPF6 (and/or other lithium compounds) improves the stability of the electrolyte solution.

  • Patent number: 5895771
    Abstract: Catalyst compositions for the polymerization of an olefin are disclosed which comprise a neutral metallocene and, as the ionizing agent an anionic aluminum-containing complex which is a fluorinated alkoxy and/or aryloxy aluminate. The fluorinated alkoxy aluminate can be of the formula A.sup.+ (Al(OR).sub.4).sup.-, where A.sup.+ is a cation capable of reacting with the neutral metallocene to produce a cationic metallocene and a non-reacting neutral species and R is a fluorinated alkyl and/or aryl group, with a representative group for A.sup.+ being (C.sub.6 H.sub.5).sub.3 C.sup.+ and with the representative fluorinated alkoxy aluminates including ?Al(OC(Ph)(CF.sub.3).sub.2).sub.4 !.sup.-, where Ph is phenyl, and ?Al(OC(CH.sub.3)(CF.sub.3).sub.2).sub.4 !.sup.-.
