AI Customer ServiceThese articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
At the pack level, the failure propagation causes problems because it may be necessary to deal with fires caused by several cells. Preventing failure propagation is important for the safety design of lithium-ion battery packs.
The FMMEA's most important contribution is the identification and organization of failure mechanisms and the models that can predict the onset of degradation or failure. As a result of the development of the lithium-ion battery FMMEA in this paper, improvements in battery failure mitigation can be developed and implemented.
This capacity fade phenomenon is the result of various degradation mechanisms within the battery, such as chemical side reactions or loss of conductivity , . On the other hand, lithium-ion batteries also experience catastrophic failures that can occur suddenly.
In May 2012, the U.S. Postal Service placed a ban on the international shipping of products with lithium-ion batteries due to fears of short circuits causing fires in the cargo compartments of airplanes . In January 2013, two separate lithium-ion battery incidents on Boeing 787 Dreamliners resulted in the grounding of the entire fleet , .
Conclusions Lithium-ion batteries are complex systems that undergo many different degradation mechanisms, each of which individually and in combination can lead to performance degradation, failure and safety issues.
