  • Inorganic Compounds as Binders for Si-Alloy Anodes 

    Congxiao Wei and M. N. Obrovac. Inorganic Compounds as Binders for Si-Alloy Anodes. J. Electrochem. Soc. (2021), 168(2), 020505.
    The inorganic compounds, lithium polysilicate (Li2Si5O11), sodium polyphosphate ((NaPO3)n), and lithium phosphate monobasic (H2LiPO4) were investigated as the sole binders in Si-alloy and graphite electrodes for Li cells. ...

  • LiF as an Alloy Component or Slurry Additive in Si-Alloy Anodes 

    Robert S. Young, Benjamin Scott, Congxiao Wei and M. N. Obrovac. LiF as an Alloy Component or Slurry Additive in Si-Alloy Anodes. J. Electrochem. Soc. (2020), 167 (16), 160524.
    Electrolyte additives are commonly used to improve electrochemical performance in Li-ion cells. The use of solids as electrolyte additives is far less common. Here, Si40'(FeSi2)(60−x)'(LiF)(x)' (' = volume percent) alloys ...

  • 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 ...
