6 FAQs about [Battery module cycle failure analysis]

What is failure mode in lithium ion batteries?

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.

What is physics-based battery failure model?

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.

What is design failure mode and effect analysis (DFMEA)?

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 .

What are failure mechanisms in lithium ion batteries?

Failure mechanisms are identified as the “processes by which 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.

Can physics-of-failure predict battery failure?

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.

How can FMMEA improve battery design & simulation?

FMMEA-enhanced design and simulation tools can enable battery manufacturers to rapidly develop new batteries by assessing the impact of chemistry and design on performance and safety. Battery system designers will also benefit from life cycle simulation capabilities that include models for all relevant failure mechanisms.
