Lithium-ion batteries (LIBs) are instrumental for electric vehicles, but safety is a concern due to thermal runaway (TR) events. In this study, an in situ observation method for TR and its propagation (TRP) in LIB electrodes is presented, employing high-frequency induction heating as the TR triggering method. The non-contact, rapid heating.

When the lithium-ion cell has an internal short circuit, the risk of thermal runaway might increase, and even battery spontaneous combustion would be triggered, endangering people's lives. Therefore, the research on foreign matter defects of lithium-ion cells is currently a hotspot.
Experiment results show that the proposed method's detection rate is improved significantly. The increase in the detection rate of foreign matter defects is beneficial to improving battery quality and safety. 1. Introduction
Undoubtedly, online monitoring of the operational status of the cell through the battery management system (BMS), to some degree, could reduce incidences of safety accidents induced by the foreign matter defect cell. However, it is more important to conduct quality control and improve the detection rate of defect cells during manufacturing.

It is generally believed that the cell with a high K -value should be abnormal, while the cell with a low K -value should be normal. Therefore, to prevent false detection, the imported OCV- K dataset of lithium-ion cells needs to be preprocessed. Firstly, sort all samples in the OCV- K dataset in descending order of K -value.
