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:
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.
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.
Given the intricate multi-layer internal structure of a LIB and the electrothermal coupling effect caused by faults, establishing a well-balanced battery model between fidelity and complexity poses a critical challenge to battery fault diagnosis.
Fault mechanisms LIBs suffer from potential safety issues in practice inherent to their energy-dense chemistry and flammable materials. From the perspective of electrical faults, fault modes can be divided into battery faults and sensor faults. 4.1. Battery faults
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.
