Customer ServicePoF 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.
The electric mode of failure can be observed as an independent event or the outcome of a mechanical mode failure. Again, ISCs are the common outcome of this mode of failure. The major electric signature of ISCs is the rapid drop in battery voltage due to contact between the internal active components of a battery .
Failure modes—the particular ways in which a system can fail—can only be defined clearly when they are observed in real-time. A detailed study of the failure will reveal what the origin of the failure is. This cause of origin can be a product of intrinsic or extrinsic stresses that affect the system.
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.
