  • 5D total scattering computed tomography reveals the full reaction mechanism of a bismuth vanadate lithium ion battery anode 
    Sottmann, Jonas; Ruud, Amund; Fjellvåg, Øystein; Vaughan, Gavin B. M.; Di Michel, Marco; Fjellvåg, Helmer; Lebedev, Oleg I.; Ponniah, Vajeeston; Wragg, David Stephen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We have used operando 5D synchrotron total scattering computed tomography (TSCT) to understand the cycling and possible long term deactivation mechanisms of the lithium-ion battery anode bismuth vanadate. This anode material ...
  • Spatial dynamics of lithiation and lithium plating during high-rate operation of graphite electrodes 
    Wragg, David; Finegan, Donal; Quinn, Alexander; Andrew, Colclasure; Xueken, Lu; Tan, Chun; Heenan, Thomas; Jervis, Rhodri; Brett, Dan J L; Das, Supratim; Gao, Tao; Cogswell, Daniel A.; Bazant, Martin; Di Michel, Marco; Checcia, Stefano; Shearing, Paul; Smith, Kandler (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The principal inhibitor of fast charging lithium ion cells is the graphite negative electrode, where favorable conditions for lithium plating occur at high charge rates, causing accelerated degradation and safety concerns. ...
