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.
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.
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.
Current strategies to address battery safety concerns mainly involve enhancing the intrinsic safety of batteries and strengthening safety controls with approaches such as early warning systems to alert users before thermal runaway and ensure user safety.
This article aims to answer some common questions of public concern regarding battery safety issues in an easy-to-understand context. The issues addressed include (1) electric vehicle accidents, (2) lithium-ion battery safety, (3) existing safety technology, and (4) solid-state batteries.
In addition to modifying intrinsic battery properties, early warning systems to detect battery failures are also vital in battery safety risk management. It is necessary to first analyze typical battery safety failure scenarios and then to select reasonable warning methods based on these scenarios.
