The Importance of Optical Fibres for Internal Temperature Sensing in Lithium-ion Batteries during Operation
Wahl, Markus Solberg; Spitthoff, Lena; Muri, Harald Ian; Jinasena, Asanthi; Burheim, Odne Stokke; Lamb, Jacob Joseph (Journal article; Peer reviewed, 2021) -
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 ... -
Internal Temperature measurements in Li-ion Pouch Cell using FBG
Østby,Frode (Master thesis, 2021)I denne masteroppgaven har det blitt forsøkt å implementert FBG-sensorer i forhåndsproduserte lithium-ion batterier for intern temperaturmåling. Det ble brukt glasskapillærer for å isolere sensorene slik at de kun regaerte ... -
Investigating the Interaction between Degradation and Thermal Behaviour in Lithium-Ion Batteries
Spitthoff, Lena (Doctoral theses at NTNU;2023:446, Doctoral thesis, 2023)The overall aim of this thesis is to generate knowledge on the interplay of battery degradation and thermal behaviour. We focused on the temperature dependency of degradation on the one hand and on the effect of degradation ... -
Liquid air energy storage – analysis and prospects
Liu, Zhongxuan; Ustolin, Federico; Spitthoff, Lena; Lamb, Jacob Joseph; Gundersen, Truls; Pollet, Bruno; Burheim, Odne Stokke (Chapter, 2020) -
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. ... -
Online Internal Temperature Sensors in Lithium-Ion Batteries: State-of-the-art and Future Trends
Jinasena, Asanthi; Spitthoff, Lena; Wahl, Markus Solberg; Lamb, Jacob Joseph; Shearing, Paul Robert; Strømman, Anders Hammer; Burheim, Odne Stokke (Peer reviewed; Journal article, 2022)The temperature of the lithium-ion battery is a crucial measurement during usage for better operation, safety and health of the battery. In-situ monitoring of the internal temperature of the cells is an important input for ... -
Peltier effects in lithium-ion battery modeling
Spitthoff, Lena; Gunnarshaug, Astrid Fagertun; Bedeaux, Dick; Burheim, Odne Stokke; Kjelstrup, Signe (Peer reviewed; Journal article, 2021)A high battery temperature has been shown to be critical for lithium-ion batteries in terms of performance, degradation, and safety. Therefore, a precise knowledge of heat sources and sinks in the battery is essential. We ... -
Product formation during discharge: a combined modelling and experimental study for Li–O2 cathodes in LiTFSI/DMSO and LiTFSI/TEGDME electrolytes
Rauter, Michael Tobias; Augustin, Matthias; Spitthoff, Lena; Svensson, Ann Mari (Peer reviewed; Journal article, 2021)Li–air or Li–O2 batteries are a promising energy storage technology due to the potentially high energy density. However, significant challenges related to reversible charge/discharge of these cells need to be solved. The ... -
