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

    Published Version: Jun Wang, Yidan Cao and M.N Obrovac. Hydrothermally Deposited Carbon Coatings for Li-Ion Battery Active Materials. J.Electrochem. Soc. (2023). Accepted manuscript. https://doi.org/10.1149/1945-7111/acf0
    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 

    Yidan Cao, Benjamin Scott, R.A. Dunlap, Jun Wang and M.N. Obrovac, An Investigation of the Fe-Mn-Si System for Li-Ion Battery Negative Electrodes, J. Electrochem. Soc., 166 (2019) A21-A26. doi: 10.1149/2.1111816jes
    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 

    113. Jun Wang and M.N Obrovac. Lab-scale Chemical Vapor Deposition onto Powders. AIP Advances, 12 (2022) 075209. doi: https://doi.org/10.1063/5.0095882
    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 

    Yijia Liu, Michael Charlton, Jun Wang, J. Craig Bennett and M. N. Obrovac. Si85 Fe15 Ox Alloy Anode Materials with High Thermal Stability for Lithium Ion Batteries. J. Electrochem. Soc. (2021), 168 (11), 110521.
    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) ...
