6 FAQs about [Failure phenomenon of new energy batteries]
Why do lithium-ion batteries fail?
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.
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 happens if a battery fails?
Catastrophic failures often result in venting of the electrolyte, fire, or explosion. This is usually due to an overstress condition where the battery is abused or operated outside of its recommended voltage, current, or temperature limits , , .
