  • Structural and Electrochemical Investigation of FexSi1-x Thin Films in Li Cells 

    Zhijia Du, R. A. Dunlap and M. N. Obrovac, Structural and Electrochemical Investigation of FexSi1-x Thin Films in Li Cells, J. Electrochem. Soc., 163 (2016) A2011-A2016.
    FexSi1-x thin films with 0 ≤ x ≤ 0.46 have been prepared by combinatorial sputtering and their electrochemical properties have been studied in Li half-cells. X-ray diffraction showed that all of the films had an amorphous ...

  • Explanation for the 4.8-V plateau LiCrxMn2-xO4 

    Obrovac, MN, Y. Gao, and JR Dahn. 1998. "Explanation for the 4.8-V plateau LiCrxMn2-xO4." Physical Review B 57(10): 5728-5733.
    Using the results of photoelectron spectroscopy (PES) measurements on LiCrxMn2-xO4 we provide an explanation for the origin of the 4.8-V plateau in Li/LiCrxMn2-xO4 cells. PES shows that the d bands derived from Mn 3d e(g) ...

  • Implications of finite-size and surface effects on nanosize intercalation materials 

    Obrovac, MN, and JR Dahn. 2000. "Implications of finite-size and surface effects on nanosize intercalation materials." Physical Review B 61(10): 6713-6719.
    A Monte Carlo simulation of a two-dimensional lattice gas with free boundaries is used to study the effects of surface and size on the chemical potential-composition curves of intercalation compounds. In particular we are ...
