Mechanically induced internal failure of lithium-ion batteries were examined. Multiple individual parameters of internal short circuit were investigated on batteries. SOC had a significant influence on battery behavior after the internal short circuit was triggered. Thickness and material of electrodes had little effect on battery mass loss rates.
Therefore, the severity of the internal short circuit of the lithium-ion battery can be analyzed and diagnosed by the CNN model. Table IV. Performance comparison of battery internal short circuit diagnosis model.
The internal short circuit was triggered by the rupture and deformation of structures within the battery, such as electrodes and separators. The higher the battery SOC, the faster the average temperature rise rate, leading to more severe thermal runaway.

During the process of internal short circuit of the battery, the heat generated by the battery will increase the internal temperature and affect the performance of the battery, 15, 16 and it is difficult to fully model the battery heat generation.
As long as the internal short-circuit parameters of the lithium-ion battery are input into the algorithm, it can be directly obtained whether the battery has an internal short-circuit or the severity of the internal short-circuit.
