  • Hydrothermally Deposited Carbon Coatings for Li-Ion Battery Active Materials Postprint 

    Obrovac, Mark N.; Wang, Jun; Cao, Yidan (IOPscience, 2023-08-14)
    Hydrothermally deposited carbon coatings were evaluated for Li-ion battery materials. The applied coatings were found to be highly uniform and porous, with a density of 1.89 g/ml and a surface area of 370 m2/g. In lithium ...
  • An Investigation of the Fe-Mn-Si System for Li-Ion Battery Negative Electrodes 

    Obrovac, MN; Cao, Yidan; Scott, Benjamin; Dunlap, R. A.; Wang, Jun (The Electrochemical Society, 2019-01-03)
    Fe-Mn-Si alloys prepared by ball milling were investigated as negative electrodes for Li-ion batteries. X-ray diffraction and room temperature 57Fe Mössbauer measurements were used to characterize alloy structure, which ...
  • Lab-scale chemical vapor deposition onto powders 

    Wang, Jun; Obrovac, Mark N. (AIP Publishing, 2022-07-06)
    In this paper, a laboratory chemical vapor deposition (CVD) reactor is described, which features an opposing screw rotating fluidized bed. The reactor efficiently concentrates powdered reactants in the reaction zone while ...
  • Si85Fe15Ox Alloy Anode Materials with High Thermal Stability for Lithium Ion Batteries 

    Obrovac, MN; Liu, Yijia; Charlton, Michael; Wang, Jun; Craig Bennett, J. (The Electrochemical Society, 2021-11-11)
    The synthesis, microstructure and electrochemical properties of ball milled Si85Fe15Ox alloys with different oxygen contents are investigated. These materials combine the features of Si-M alloys (low irreversible capacity) ...
