    • Review - Reversible heat effects in cells relevant for lithium-ion batteries 

      Gunnarshaug, Astrid Fagertun; Vie, Preben Joakim Svela; Kjelstrup, Signe (Peer reviewed; Journal article, 2021)
      We review measurements of reversible heat effects in lithium-ion batteries, i.e. entropy changes and Seebeck coefficients of cells with relevant electrodes. We show how to compute the Peltier heat of battery electrodes ...

    • Single Electrode Entropy Change for LiCoO2 Electrodes 

      Richter, Frank; Gunnarshaug, Astrid Fagertun; Burheim, Odne Stokke; Vie, Preben Joakim Svela; Kjelstrup, Signe Helene (Journal article, 2017)
      Heat effects are known to be crucial for the performance of the Li-battery. In addition to the irreversible effects (e.g. Joule heat), reversible heat effects may play a role. These effects, i.e. the Soret and Seebeck ...

    • Thermal conductivity and internal temperature profiles of Li-ion secondary batteries 

      Richter, Frank; Kjelstrup, Signe; Vie, Preben Joakim Svela; Burheim, Odne Stokke (Journal article, 2017)
      In this paper we report the thermal conductivity for several battery components. Materials were obtained from several electrode- and separator suppliers, and some were extracted from commercial batteries. We measured with ...

    • Thermal Conductivity, Heat Sources and Temperature Profiles of Li-ion Batteries 

      Burheim, Odne Stokke; Onsrud, Morten Andreas; Pharoah, John George; Vullum-Bruer, Fride; Vie, Preben Joakim Svela (Journal article; Peer reviewed, 2014)
      In this paper we report the thermal conductivity of several commercial and non-commercial Li-ion secondary battery electrode materials with and without electrolytesolvents. We also measure the Tafel potential, the ohmic ...
