  • Electrochemistry and Thermal Behavior of SiOx Made by Reactive Gas Milling 

    Obrovac, MN; Cao, Yidan; Dunlap, R. A. (The Electrochemical Society, 2020-06-30)
    SiOx with various oxygen contents were synthesized from Si powder by a simple room-temperature ball milling method by controlling the air exposure time during milling. The resulting SiOx consists of nano and amorphous Si ...

  • 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 ...

  • Li Insertion in Ball Milled Si-Mn Alloys 

    Obrovac, MN; Cao, Yidan; Craig Bennett, J; Dunlap, R. A. (The Electrochemical Society, 2018-06-08)
    Si1-xMnx (0 ≤ x ≤0.5, x=0.05)alloyswereprepared by ball milling and studied as negative electrode materials in Li cells. These alloys were found to be unique amongtransition metals. When x ≤ 0.35, the alloys are essentially ...
