    • Crystallinity of silicon nanoparticles: Direct influence on the electrochemical performance of lithium ion battery anodes 

      Ulvestad, Asbjørn; Reksten, Anita; Andersen, Hanne Flåten; Almeida Carvalho, Patricia; Jensen, Ingvild Julie Thue; Nagell, Marius Uv; Mæhlen, Jan Petter; Kirkengen, Martin; Koposov, Alexey (Peer reviewed; Journal article, 2020)
      The use of silicon (Si) in the form of nanoparticles is one of the most promising routes for boosting the capacity of modern Li‐ion batteries. Many parameters influence the performance of Si making the comparison of materials ...

    • MgH2–CoO: a conversion-type composite electrode for LiBH4-based all-solid-state lithium ion batteries 

      El-Kharbachi, Abdelouahab; Uesato, Hiroki; Kawai, Hironori; Wenner, Sigurd; Miyaoka, Hiroki; Sørby, Magnus Helgerud; Fjellvåg, Helmer; Ichikawa, Takayuki; Hauback, Bjørn (Journal article; Peer reviewed, 2018)
      Several studies have demonstrated that MgH2 is a promising conversion-type anode toward Li. A major obstacle is the reversible capacity during cycling. Electrochemical co-existence of a mixed metal hydride-oxide conversion ...

    • Non-​Nucleophilic Electrolyte Based on Ionic Liquid and Magnesium Bis(diisopropyl)​amide for Rechargeable Magnesium-​Ion Batteries 

      Kallidanthiyil Chellappan, Lethesh; Kvello, Jannicke Hatlø; Tolchard, Julian R; Dahl, Paul Inge; Hanetho, Sidsel Meli; Berthelot, Romain; Fiksdahl, Anne; Jayasayee, Kaushik (Peer reviewed; Journal article, 2020)
      A non-nucleophilic electrolyte for rechargeable Mg-ion batteries is developed by the reaction of magnesium bis(diisopropyl)amide and 1-ethyl-3-methylimidazolium tetrachloroaluminate ionic liquid in tetrahydrofuran solvent. ...

    • Recycling of the Rare Earth Oxides from Spent Rechargeable Batteries Using Waste Metallurgical Slags 

      Tang, Kai; Ciftja, Arjan; Eijk, Casper van der; Wilson, Shawn C.; Tranell, Gabriella (Journal article; Peer reviewed, 2013)
      A high temperature process for recycling spent nickel-metal hydride rechargeable batteries has been recently developed at SINTEF/NTNU. The spent battery modules were first frozen with liquid nitrogen for the de-activation ...

    • Silicon-carbon composite anodes from industrial battery grade silicon 

      Foss, Carl Erik Lie; Andersen, Hanne Flåten; Ulvestad, Asbjørn; Kirkengen, Martin; Vullum, Per Erik; Voje, Jorunn; Tronstad, Ragnar; Mokkelbost, Tommy; Mæhlen, Jan Petter (Journal article; Peer reviewed, 2019)
      In this work, silicon/carbon composites for anode electrodes of Li-ion batteries are prepared from Elkem’s Silgrain® line. Gentle ball milling is used to reduce particle size of Silgrain, and the resulting Si powder consists ...
