Additionally, any excessive external pressure to the edge of the cell could cause a short circuit. This article will focus on the testing for burrs and particles inside the materials of lithium ion batteries. Figure 3.
External short circuit (ESC) faults pose severe safety risks to lithium-ion battery applications. The ESC process presents electric thermal coupling characteristics and becomes more complex when the batteries operate in large group, which often lead to serious consequences.
Internal short circuit (ISCr) is regarded as one of the major safety risks for the lithium-ion batteries. While most of the ISCr incidents only result in poor battery performance, some of them do lead to the thermal runaway and may further results in fatal accidents, 1, 2 which are unaffordable for consumers.
The circuit model for battery can be expressed as Eq. (1), where Up represents the polarization voltage, Ut denotes the terminal voltage, and I signifies the current . 2).
