Simultaneous Thermal Analysis (STA)/Fourier Transform Infrared (FTIR) spectrometer/Gas Chromatography Mass Spectrometry (GC-MS) were used to reveal thermal events and to detect evolved gases. Chemistry The Effect of Charging and Discharging Lithium Iron Phosphate-graphite Cells at Different Temperatures on Degradation Vanesa Ruiz Ruiz1, Akos Kriston1, Ibtissam Adanouj1, Matteo Destro2, Daniela Fontana2, Andreas Pfrang1 1Directorate for Energy, Transport & Climate, Energy Storage Unit, European Commission, Joint Research Centre (JRC), 2Lithops S.r.l This article describes the effect of dissimilar charging/discharging temperatures on the degradation of lithium iron phosphate-graphite pouch cells, aiming at simulating close to real case scenarios. In total, 10 temperature combinations are investigated in the range -20 to 30 °C in order to analyze the impact of temperature on degradation.
