  • Benefits and Development Challenges for Conversion-Alloying Anode Materials for Na-Ion Batteries 
    Skurtveit, Amalie; Brennhagen, Anders; Park, Heesoo; Cavallo, Carmen; Koposov, Alexey (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Over the past decade, Na-ion batteries (NIBs) have gained a substantial interest within the research community and relevant industry. NIBs are now emerging as a cost-effective and sustainable alternative to modern Li-ion ...
  • Bi metallates as conversion-alloying anodes for Na-ion batteries 
    Brennhagen, Anders (Doctoral thesis / Doktoravhandling, 2024)
    Rechargeable batteries are essential for the green energy transition and Li-ion batteries (LIBs) are currently dominating the marked. Li and other elements used in LIBs are limited resources on the planet, which makes them ...
  • High power iron phosphate cathodes by atomic layer deposition 
    Brennhagen, Anders; Kvamme, Kristian Breivik; Sverdlilje, Katja S. S.; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Amorphous thin films of FePO4 and Fe4(P2O7)3 show excellent power capabilities and good stability as cathode materials in Li-ion batteries. Within our tested range of materials, 10 nm FePO4 shows the best results and can ...
  • Operando XRD studies on Bi2MoO6 as anode material for Na-ion batteries 
    Brennhagen, Anders; Cavallo, Carmen; Wragg, David Stephen; Ponniah, Vajeeston; Sjåstad, Anja Olafsen; Koposov, Alexey; Fjellvåg, Helmer (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Based on the same rocking-chair principle as rechargeable Li-ion batteries, Na-ion batteries are promising solutions for energy storage benefiting from low-cost materials comprised of abundant elements. However, despite ...
  • Synthesis and electrochemical characterization of thin film iron phosphates as cathode material for Li-ion batteries 
    Brennhagen, Anders (Master thesis / Masteroppgave, 2019)
    Solid-state batteries is one of the main contenders for domination of the future battery marked. Thin film technology is important in the development of these batteries. In this work, we have shown that amorphous thin film ...
  • Tracking Lithiation of Si-Based Anodes in Real Time by Total Scattering Computed Tomography 
    Wragg, David Stephen; Skautvedt, Casper; Brennhagen, Anders; Geiss, Carina; Checchia, Stefano; Koposov, Alexey (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    The existing set of characterization tools does not permit a full description of the three-dimensional (3D) structure and operating mechanisms of amorphous, low-scattering alloying active materials in metal-ion batteries. ...
  • Understanding the (De)Sodiation Mechanisms in Na‐Based Batteries through Operando X‐Ray Methods 
    Brennhagen, Anders; Cavallo, Carmen; Wragg, David; Sottmann, Jonas; Koposov, Alexey; Fjellvåg, Helmer (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Progress in the field of Na‐based batteries strongly relies on the development of new advanced materials. However, one of the main challenges of implementing new electrode materials is the understanding of their mechanisms ...
  • Unraveling the (De)sodiation Mechanisms of BiFeO3 at a High Rate with Operando XRD 
    Brennhagen, Anders; Skautvedt, Casper; Cavallo, Carmen; Wragg, David Stephen; Koposov, Alexey; Sjåstad, Anja Olafsen; Fjellvåg, Helmer (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Development of new anode materials for Na-ion batteries strongly depends on a detailed understanding of their cycling mechanism. Due to instrumental limitations, the majority of mechanistic studies focus on operando ...
