Fig. 6: Thermal runaway of Gr|NMC811 battery with non-flammable concentrated LiFSI/TMP.
From: Thermal runaway of Lithium-ion batteries employing LiN(SO2F)2-based concentrated electrolytes
a The temperature dependence of dT/dt of the Gr|NMC811 battery with the concentrated LiFSI/TMP. The inset shows the combustibility of battery in the lateral heating test. b DSC trace and TGA curve of the An+LiFSI/TMP sample. c NO2(m/z = 46) and SO2(m/z = 64) gas evolution of the An+LiFSI/TMP sample. d Illustration of the proposed thermal runaway mechanism of LiFSI-based concentrated electrolytes in Gr|NMC batteries. The considerable heat generated by the reaction of LiFSI+LiC6 triggers the Gr|NMC batteries to thermal runaway.
