Abstract:

Lithium-ion batteries used for energy storage face significant risks. These include overcurrent induced by conduction and induction, and surge currents caused by device failures when integrated into the grid or hybrid systems. However, the temperature rise response of lithium-ion cells under surge current impulses remains poorly understood. This study investigates the temperature behavior of cylindrical ternary lithium-ion cells subjected to surge current impulses of varying amplitudes. Both typical multipoint temperature measurements and three-dimensional infrared observations were employed to analyze the dynamic temperature rise response of the cells. In addition, an electrochemical coupled finite element simulation model was developed to clarify the temperature rise characteristics of the cells. The results indicate that surge currents with waveforms of 8/20 μs and peak values of 7.4, 10.6, and 13.0 kA lead to temperature rises of 0.7 ℃, 1.8 ℃, and 4.2 ℃ at the cell surface, respectively. Notably, surge currents with higher peak values (≥10.6 kA) cause the cathode region to exhibit a higher temperature compared to the anode region, while the separator experiences the lowest temperature rise.
