Additionally, for the study of lithium-ion batteries with internal short circuits, we need to pay more attention to the maximum temperature and temperature rise rate of the battery. In this section, experiments and analysis were conducted on cells A and B at 40 % SOC without thermal runaway.
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.
Fig. 16 presents the ESC test results of 6-series battery modules from Groups 6 and 7. Upon triggering the short circuit, the short current rapidly escalates to 150 A, and the module voltage plummets to approximately 0.5 V, as illustrated in Fig. 16 (A) and (B).
For thick electrodes, a large amount of Li + will preferentially intercalate into the material particles in the upper layer of the cathode during a short circuit, causing the volume of the lithiated region to expand while the non-lithiated region remains unchanged.
Among all the known types of battery failure modes, the internal short circuit (ISC) tops the list of the major safety concerns for the lithium-ion battery. However, a clear picture of the LIB's electrochemical safety behavior in the context of the ISC remains to be fully established.
Once the temperature of LiBs surpasses 90 °C, the exothermic chemical reactions within the battery accelerate, initiating a positive feedback loop of increased heat generation. The escalating temperature can lead to thermal runaway, ultimately resulting in fires and explosions [2, 3].

Short Circuiting a Battery: What Happens Next
Short circuiting a battery means excessive current follows an unintended path, due to an abnormal connection with little or no impedance. This condition allows an excessively high current to flow with little resistance. An uncontrolled surge of energy can damage the circuit, and result in overheating, skin burns, fire, and even explosion.
