• On the electrokinetic characterization of charged polymeric membranes by transversal streaming potential 

      Barragán, V. María; García Villaluenga, Juan Pedro; Izquierdo-Gil, Maria Amparo; Kristiansen, Kim (Peer reviewed; Journal article, 2021)
      The effect of a transmembrane pressure on the electrokinetic properties of different polymeric charged membranes is analysed. Electrokinetic characterization can involve the application of increasing or decreasing pressure ...
    • Reversible heat effects of lithium metal- and porous lithium iron phosphate electrodes 

      Gunnarshaug, Astrid Fagertun; Burheim, Odne Stokke; Kjelstrup, Signe (Peer reviewed; Journal article, 2023)
      We report Peltier heats and reaction entropy of cells with lithium metal- and near fully lithiated lithium iron phosphate (LFP) electrodes. The Peltier heats were measured through the Seebeck coefficient of thermogalvanic ...
    • Seebeck coefficients of cells with lithium carbonate and gas electrodes 

      Børset, Marit Takla; Kang, Xue; Burheim, Odne Stokke; Haarberg, Geir Martin; Xu, Q.; Kjelstrup, Signe (Journal article; Peer reviewed, 2015)
      The Seebeck coefficient is reported for thermoelectric cells with gas electrodes and a molten electrolyte of one salt, lithium carbonate, at an average temperature of 750 °C. We show that the coefficient, which is 0.88 mV ...
    • Seebeck coefficients of cells with molten carbonates relevant for the metallurgical industry 

      Kang, X.; Børset, Marit Takla; Burheim, Odne Stokke; Haarberg, Geir Martin; Xu, Q.; Kjelstrup, Signe (Journal article; Peer reviewed, 2015)
      We report Seebeck coefficients of electrochemical cells with molten carbonate mixtures as electrolytes and carbon dioxide|oxygen electrodes. The system is relevant for use of waste heat and off-gases with concentration of ...
    • The reversible heat effects at lithium iron phosphate- and graphite electrodes 

      Gunnarshaug, Astrid Fagertun; Kjelstrup, Signe; Bedeaux, Dick; Richter, Frank; Burheim, Odne Stokke (Journal article; Peer reviewed, 2019)
      Lithium ion batteries are used to store and produce electric energy. During the charging- and discharging processes, net heat is released or adsorbed in the battery. Temperature is one of the most important factors for ...
