    • 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 ...
    • 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 ...
    • Measurements of hydrocarbon flame propagation in a channel 

      Åkervik, Espen; Fossum, Hannibal E.; Henriksen, Mathias; Bjerketvedt, Dag (2021-05-25)
      Assessing the risk of gas explosions associated with Li-ion batteries in confined geometries is challenging. When a Li-ion battery cell undergoes so-called thermal runaway, internal reactions in the cell can lead to the ...
