    • Explosion characteristics for Li-ion battery electrolytes at elevated temperatures 

      Henriksen, Mathias; Vågsæther, Knut; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, Dag (2019-01-28)
      Li-ion batteries are used in electronic devices and electric cars, yet they create safety concerns due to the possibility of the release of combustible materials. The electrolyte, one of the main components in a Li-ion ...
    • In operando neutron diffraction study of a commercial graphite/(Ni, Mn, Co) oxide-based multi-component lithium ion battery 

      Sainudeen Nazer, Nazia; Yartys, Volodymyr; Azib, Tahar; Latroche, Michel; Cuevas, Fermìn; Forseth, Sissel; Vie, Preben Joakim Svela; Denys, Roman Volodymyrovich; Sørby, Magnus Helgerud; Hauback, Bjørn; Arnberg, Lars; Henry, Paul F. (2016)
      In situ neutron diffraction was employed to investigate the structural evolution of the electrode materials in an ICR 10440 commercial cylindrical lithium-ion battery, which has a discharge capacity of 360 mAh and a nominal ...
    • (Invited) Changes in Thermal Stability of Cyclic Aged Commercial Lithium-Ion Cells 

      Lian, Torleif; Vie, Preben Joakim Svela; Gilljam, Martin; Forseth, Sissel (2019)
      Thermal stability is one of several factors affecting the safety properties of lithium-ion cells. The thermal stability for uncycled cells is well-documented, but the effect of cyclic ageing on thermal stability is far ...
    • Laminar burning velocity of gases vented from failed Li-ion batteries 

      Henriksen, Mathias; Vaagsaether, K.; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, D. (2021-06-10)
      In the last decade, several fires and explosions caused by Li-ion batteries (LIBs) have been reported. This can be attributed to the thermal runaway and catastrophic failures of LIBs that release combustible gases, which ...
    • Laminar burning velocity of the dimethyl carbonate–air mixture formed by the Li-ion electrolyte solvent 

      Henriksen, Mathias; Vågsæther, Knut; Gaathaug, Andre Vagner; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, Dag (2020-08-21)
      If a Li-ion cell fails and the electrolyte leaks out into air, a flammable premixed gas cloud can be formed. The electrolyte combustion energy is 65–70% of the total energy content of the cell. The main objective of this ...
    • Oppvarming av litium- og litiumionceller 

      Forseth, Sissel; Johannessen, Tom C.; Hasvold, Øistein (2006)
      Lithium cells may for safety purposes be equipped with safety vents, shut down separators and various types of fuses. In this work lithium primary cells, lithium ion cells and a lithium ion polymer battery block have been ...
    • Safety aspects of large lithium batteries 

      Hasvold, Øistein; Forseth, Sissel; Johannessen, Tom C.; Lian, Torleif (2007)
      A battery containing 294 cells in the form of 7 modules of 42 DD lithium / sulfuryl chloride cells in a 7S6P configuration exploded during in-line inspection pigging of a 30” gas pipeline in April 1999. The gas pressure ...
