Abstract

Thermal characteristics of lithium ion batteries are particularly important for both the optimization of the battery cells and design of the thermal management system for battery packs. The Si-C composite applied in lithium ion battery could improve the battery's energy density. For a 3 Ah pouch lithium ion battery with NCM/Si-C composite material system, the thermal characteristics were analyzed during the charging and discharging processes using the Extended Volume-Accelerating Rate Calorimeter. Meanwhile a 3 Ah pouch lithium ion battery with NCM/graphite composite material system was used as the reference sample. The internal resistance has great influence on the thermal behavior of Li-ion batteries. Thus, internal resistances of the battery cell were measured using the electrochemical impedance spectroscopy (EIS) method. Experimental results showed that the battery cell with NCM/Si-C generated much more amount of heat during charging and discharging processes. Temperature rise and heat generation power of the batteries increased as the current rate rising during charging and discharging processes. In addition, the overall internal resistance obtained by EIS had a close relationship with the heat generation behavior.
