• Dipentamethylene thiuram tetrasulfide-based cathodes for rechargeable magnesium batteries 

      Kaland, Henning; Hadler-Jacobsen, Jacob; Fagerli, Frode Håskjold; Wagner, Nils Peter; Schnell, Sondre Kvalvåg; Wiik, Kjell (Peer reviewed; Journal article, 2020)
      Rechargeable Mg batteries (RMBs) represent a possible route for low-cost energy storage applications, but they are lacking a satisfactory cathode material. Conventional sulfur (S8) cathodes have shown promise, yet they ...
    • On the Solubility of Bi in Tetragonal Tungsten Bronzes 

      Zeiger, Caren Regine; Williamson, Benjamin Albert Dobson; Walker, Julian Bradley; Einarsrud, Mari-Ann; Grande, Tor (Peer reviewed; Journal article, 2024)
      Ferroelectric Pb5Nb10O30 (PN) tetragonal tungsten bronze (TTB) forms solid solutions that exhibit morphotropic phase boundaries (MPBs). Successful replacement of PN with TTBs containing Bi could advance lead-free TTB MPBs. ...
    • Origin of ferroelectric polarization in tetragonal tungsten-bronze-type oxides 

      Olsen, Gerhard Henning; Aschauer, Ulrich; Spaldin, Nicola A.; Selbach, Sverre Magnus; Grande, Tor (Journal article; Peer reviewed, 2016)
      The origin of ferroelectric polarization in tetragonal tungsten-bronze- (TTB-) type oxide strontium barium niobate (SBN) is investigated using first-principles density functional calculations. We study in particular the ...
    • Performance Study of MXene/Carbon Nanotube Composites for Current Collector- and Binder-Free Mg-S Batteries 

      Kaland, Henning; Fagerli, Frode Håskjold; Hadler-Jacobsen, Jacob; Zhao-Karger, Zhirong; Fichtner, Maximilian; Wiik, Kjell; Wagner, Nils Peter (Peer reviewed; Journal article, 2021)
      The realization of sustainable and cheap Mg-S batteries depends on significant improvements in cycling stability. Building on the immense research on cathode optimization from Li-S batteries, for the first time a beneficial ...
