  • 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 (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 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 ...
  • Stoichiometry-Controlled Reversible Lithiation Capacity in Nanostructured Silicon Nitrides Enabled by in Situ Conversion Reaction 
    Ulvestad, Asbjørn; Skare, Marte Orderud; Foss, Carl Erik Lie; Krogsæter, Henrik; Reichstein, Jakob; Preston, Thomas J.; Mæhlen, Jan Petter; Andersen, Hanne Flåten; Koposov, Alexey (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    In modern Li-based batteries, alloying anode materials have the potential to drastically improve the volumetric and specific energy storage capacity. For the past decade silicon has been viewed as a “Holy Grail” among these ...
