    Abstract: Improved nonaqueous electrolytes have been developed for lithium ion batteries. The electrolytes comprises a lithium salt, a nonaqueous carbonate solvent, and an additive mixture comprising at least one group A compound, at least one group B compound, and at least one group C compound wherein the group A compound is selected from the group consisting of VC and PES, the group B compound is selected from the group consisting of MMDS, DTD, TMS, ES, and PS, and the group C compound is selected from the group consisting of TTSP and TTSPi. Certain ternary or quaternary additive mixtures can: reduce parasitic reactions at the positive electrode above 4.1 V compared to use of VC alone; increase the thermal stability of a charged graphite electrode at elevated temperature; improve coulombic efficiency; and also reduce impedance of the batteries. These factors all suggest longer lived, safer, higher power lithium batteries with better tolerance to high voltages which will improve energy density.

    Abstract: Nanostructured thin film catalysts which may be useful as fuel cell catalysts are provided, the catalyst materials including intermixed inorganic materials. In some embodiments the nanostructured thin film catalysts may include catalyst materials according to the formula PtxM(1-x) where x is between 0.3 and 0.9 and M is Nb, Bi, Re, Hf, Cu or Zr. The nanostructured thin film catalysts may include catalyst materials according to the formula PtaCobMc where a+b+c=1, a is between 0.3 and 0.9, b is greater than 0.05, c is greater than 0.05, and M is Au, Zr, or Ir. The nanostructured thin film catalysts may include catalyst materials according to the formula PtaTibQc where a+b+c=1, a is between 0.3 and 0.9, b is greater than 0.05, c is greater than 0.05, and Q is C or B.
