Anodes for Li‑ion batteries prepared from microcrystalline silicon and enabled by binder’s chemistry and pseudo‑self‑healing
Foss, Carl Erik Lie; Stephan, Müssig; Svensson, Ann Mari; Vie, Preben Joakim Svela; Ulvestad, Asbjørn; Mæhlen, Jan Petter; Koposov, Alexey (Peer reviewed; Journal article, 2020)Silicon, while suffering from major degradation issues, has been recognized as a next promising material to replace currently used graphite in the anodes of Li-ion batteries. Several pathways to mitigate the capacity fading ... -
Incremental capacity analysis (dQ/dV) as a tool for analysing the effect of ambient temperature and mechanical clamping on degradation
Spitthoff, Lena; Vie, Preben Joakim Svela; Wahl, Markus Solberg; Wind, Julia; Burheim, Odne Stokke (Peer reviewed; Journal article, 2023)This work presents a comprehensive degradation study of two types of large lithium-ion pouch cells; 26 NMC532/Graphite (64 Ah) and 9 NMC433/Graphite (31 Ah) pouch cells. The cells were degraded under different cycling ... -
On the Relations between Lithium-Ion Battery Reaction Entropy, Surface Temperatures and Degradation
Spitthoff, Lena; Wahl, Markus Solberg; Lamb, Jacob Joseph; Shearing, Paul Robert; Vie, Preben Joakim Svela; Burheim, Odne Stokke (Peer reviewed; Journal article, 2023)Understanding and mitigating the degradation of batteries is important for financial as well as environmental reasons. Many studies look at cell degradation in terms of capacity losses and the mechanisms causing them. ... -
Operando neutron imaging study of a commercial Li-ion battery at variable charge-discharge current densities
Nazer, Nazia S.; Strobl, Markus; Kaestner, Anders; Vie, Preben Joakim Svela; Yartys, Volodymyr (Peer reviewed; Journal article, 2022)We report an operando neutron imaging study of a commercial ICR 10440 Li ion battery during charge and discharge. The cylindrical battery with a spiral configuration is composed of a multiphase layered oxide cathode and ... -
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 ... -
Thermal transport in lithium-ion batteries: The effect of degradation
Spitthoff, Lena; Wahl, Markus Solberg; Vie, Preben Joakim Svela; Burheim, Odne Stokke (Peer reviewed; Journal article, 2023)In this work, we report thermal conductivities of pristine and degraded electrodes, from commercial lithium-ion batteries. The thermal conductivities were measured with and without electrolyte solvent and at different ...
