Figure 3

(a) Schematic illustration of the working principle of ARC (BTC130, HEL) with a small bomb chamber. Temperature profiles when (b) dual‐salt electrolyte, (c) 100% SOC cathode/electrolyte, (d) 0% SOC cathode/electrolyte, (g) 100% SOC anode/electrolyte, and (h) 0% SOC anode/electrolyte, are tested by the heat‐wait‐search (HWS) mode of ARC. The insets in (b,c,d,g,h) are the determined components percentage in collected gas after ARC testing. XRD patterns of (e), (f) cathode and (i) anode by increasing the temperature from 30 to 400°C. The anode and cathode are carefully and separately dissembled from fully charged (100% SOC) and fully discharged (0% SOC) 5 Ah NCM523/G pouch cells.
