These 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.
Li-ion battery failures. A critical step in this process is the understanding of the root cause for failures so that practices and procedures can be implemented to prevent future events. Battery Failure Analysis spans many different disciplines and skill sets. Depending on the nature of the failure, any of the following may come into play:
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.
The fundamental structure of a lithium-ion cell is shown in Fig. 1. A lithium-ion battery consists of this cell-sandwich structure packaged in several different form factors such as cylindrical, coin, pouch, and prismatic.
In principle, destructive and non-destructive analysis methods can be used to detect defects in batteries, although only the latter are reasonable in the production environment of the value chain as they do not degrade battery performance [35].
PoF is not the only type of physics-based approach to model battery failure modes, performance, and degradation process. Other physics-based models have similar issues in development as PoF, and as such they work best with support of empirical data to verify assumptions and tune the results.
