Safety assessment of electrically cycled cells at high temperatures under mechanical crush loads

An ageing test procedure was developed in this work in order to assess the influence of battery degradation effects, occurring during electrical cycling of lithium-ion batteries at elevated temperatures, on the electrical and mechanical properties of the cells and on their safety behaviour under mechanical quasi-static crush loading. Commercial 41 A h NMC-LMO/graphite pouch cells were charged and discharged at 60 °C for 700 cycles at 1 C in an...
