  • Spherically Smooth Cathode Particles by Mechanofusion Processing 

    Lituo Zheng, Congxiao Wei, M. D. L. Garayt, Judy MacInnis, and M. N. Obrovac, Spherically Smooth Cathode Particles by Mechanofusion Processing, J. Electrochem. Soc., 166 (2019) A2924-A2927.
    Surface modification has been shown to be useful for improving the cycling performance of cathode materials. Typically hetero-compositional coatings are applied on cathode particle surfaces using methods, such as aqueous ...

  • Stabilizing NaCrO2 by Sodium Site Doping with Calcium 

    Lituo Zheng, J. C. Bennett, and M. N. Obrovac, Stabilizing NaCrO2 by Sodium Site Doping with Calcium, J. Electrochem. Soc., 166 (2019) A2058 - A2064.
    Layered cathode materials based on abundant, low cost raw materials have garnered interest in recent years. O3-type NaCrO2 is a promising cathode material as it offers decent energy density and is easy to synthesize. In ...

  • 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 ...

  • Synthesis, Lithium Insertion and Thermal Stability of Si–Mo Alloys 

    Simeng Cao, Shayne Gracious, J. Craig Bennett and M. N. Obrovac. Synthesis, Lithium Insertion and Thermal Stability of Si–Mo Alloys. J. Electrochem. Soc. (2020), 167 (13), 130531.
    Li insertion was investigated in SixMo100−x (90 ≥ x ≥ 70, Δx = 10) alloys prepared by mechanical ball milling. X-ray diffraction (XRD) and quantitative phase analysis were used to analyze phase compositions of these Si–Mo ...
