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:
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.
Design failure mode and effect analysis (DFMEA) focuses on potential failure modes that are caused by the specifications and design parameters finalized in the design phase. While designing a lithium-ion battery, the general requirements for lithium-ion battery abuse tolerance also need to be considered .
The failure modes with higher risk are prioritized and strategies like engineering controls, design modifications, process improvements and enhanced quality control measures are implemented to minimize the occurrence or impact of the failure mode . Cylindrical lithium-ion batteries are complex systems with multi-step manufacturing processes.
This enables a physics-of-failure (PoF) approach to battery life prediction that takes into account life cycle conditions, multiple failure mechanisms, and their effects on battery health and safety. This paper presents an FMMEA of battery failure and describes how this process enables improved battery failure mitigation control strategies. 1.
