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.
Once the temperature of LiBs surpasses 90 °C, the exothermic chemical reactions within the battery accelerate, initiating a positive feedback loop of increased heat generation. The escalating temperature can lead to thermal runaway, ultimately resulting in fires and explosions [2, 3].
Multiple requests from the same IP address are counted as one view. The internal short circuit (ISC) in lithium-ion batteries is a serious problem since it is probably the most common cause of a thermal runaway (TR) that still presents many open questions, even though it has been intensively investigated.
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.
The most likely mechanism of short here seems to be the physical deformation of the battery which leads to a conductive path between the electrodes. The abused batteries are then cycled in the devices and the testing data are logged. Batteries developing ISC due to drop is a probabilistic event.
Among all the known types of battery failure modes, the internal short circuit (ISC) tops the list of the major safety concerns for the lithium-ion battery. However, a clear picture of the LIB's electrochemical safety behavior in the context of the ISC remains to be fully established.
