文摘

Comprehensive study on the thermal stability of commercial 18650-type LIBs. Strong influence of cycling temperature on the thermal stability of the SEI. Onset temperatures for exothermic reactions correlate with SOC for fresh LIBs. Metallic lithium deposits on the anode reduce safety properties of the cell. Thermally stable SEI impedes de-intercalation of lithium ions.
