  • Combinatorial Study of the Si-Sn-O System as Negative Electrode Materials in Li-Ion Cells 

    Xiuyun Zhao, M.T. Schreiber, L. MacEachern, R.J. Sanderson, R.A. Sanderson, R.A. Dunlap and M.N. Obrovac, Combinatorial Study of the Si-Sn-O System as Negative Electrode Materials in Li-Ion Cells, J. Electrochem. Soc., 163 (2016), A203-A209.
    SixSnyO1-x-y films with 0.45 < x < 0.80, 0.05 < y < 0.35, and 0.05 < (1-x-y) < 0.40 have been prepared using a magnetron sputtering method. All compositions had an amorphous structure and good capacity retention. Reversible ...
  • Electrochemistry of Catalytically Graphitized Ball Milled Carbon in Li Batteries 

    High carbon Fe-C composites with starting concentrations of 10, 20, 30, and 40 wt% Fe (2.3 - 12.5 atomic % Fe) were prepared by ball milling followed by annealing. Increasing the Fe concentration and annealing temperature ...
