Internal short circuit (ISC) of lithium-ion batteries (LIBs) would be triggered due. to inevitable electric vehicle collision, which pose serious threats to the safety and stability of the battery system. However, there is a lack of research on the ISC mechanism of LIBs under dynamic impact loadings.
Other than the issues mentioned above, the internal short circuit (ISC) is the common feature before TR, which enormously influences the performance and safety of LIBs. In this paper, the formation mechanisms, evolution framework, experimental approaches, and detection methods of ISC are summarized in detail and analyzed comprehensively.
The battery internal short circuit (ISCr) is one of the major obstacles that impede the improvement of the battery safety. Although most of the ISCr incidents only lead to the loss of battery energy and the decline of the battery performance, some of the ISCr incidents do result in the battery thermal runaway accidents (4).
When ISC occurs, the internal temperature of the battery increases, which promotes the internal chemical reaction. The first exothermic reaction is the decomposition of SEI layer, which is generally considered to occur at 80-120 °C .
Conventional experimental approaches are mainly used to simulate the cell performance when the cell suffers from applied force, such as collision or penetration. Among the current battery safety test standards, mechanical abuse tests, especially penetration and crush, are frequently employed to simulate the ISC process .
The mechanical-electrical-thermal behaviors of LIBs in quasi-static and dynamic loading are compared. A triggering impact energy map of each ISC mode for LIBs with various SOCs is established. Internal short circuit (ISC) of lithium-ion batteries (LIBs) would be triggered due.
