Aluminum foil is widely used for the soft pack of lithium batteries in consumer electronics, new energy vehicles, and energy storage applications. HDM''s battery soft pack foil protects personal safety, and in the event of a safety hazard the soft pack battery will at most bulge and crack, rather than explode like a steel-cased aluminum-cased battery cell.

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.
Through intentionally making defect batteries, aging experiments, and characterization analysis at different stages, the evolution mechanism of foreign matter defect in the battery is revealed. The self-induced internal-short-circuit fusing and sudden spontaneous combustion of the battery under non-abuse are all reproduced.
The battery damage situation caused by the foreign matter of different particle sizes during the battery production process is revealed. Through the non-abuse aging cycle test, we reproduced the SSC and the self-induced ISC fusing of lithium-ion cells. Then through the analysis of the test data, we propose the early warning method for SSC.
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
In order to avoid the generation of batteries containing foreign matter as much as possible, battery manufacturers need to establish a complete and strict raw material detection mechanism, workshop cleaning mechanism, insulation withstand voltage (Hi-pot) test mechanism, and self-discharge test mechanism.
In order to reduce the outflow of such foreign matter defect cells, the production line universally adopted the K -value test process. In the traditional K -value test, the detection threshold is determined empirically, which has poor dynamic characteristics and probably leads to missing or false detection.
