6 FAQs about [Analysis of the source of foreign matter in battery production]
What is the evolution mechanism of foreign matter defect in a battery?
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.
How to avoid the generation of batteries containing foreign matter?
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.
Does foreign matter affect battery performance and safety?
As the battery manufacturing innovation is mainly concentrated in enterprises, there is little public literature related to them due to factors such as confidentiality [23, 24]. The research on the impact of foreign matter on battery performance and safety is even rarer.
