After an internal short circuit occurs, batteries with thicker electrodes exhibit a larger number of broken particles in the cathode material and a higher degree of surface roughness on the broken particles. After an internal short circuit occurs, the intensity of the internal electrochemical reactions in NCM far exceeds that of LFP.
By comparing the curves, it is also found that the higher the SOC, the smaller the displacement corresponding to the short circuit, indicating that high SOC batteries are more prone to internal short circuits when subjected to external force and displacement.
