AI Customer ServiceOver time, these batteries can fail, either through a gradual loss of charge or through the inability to work under tough environmental conditions, leading to more catastrophic failures that cause fires or explosions. Palacin and de Guibert review such failures and suggest that, although often chemistry-specific, common causes can be found.
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.
2016 Feb 5;351 (6273):1253292. doi: 10.1126/science.1253292. Copyright © 2016, American Association for the Advancement of Science. Battery failure and gradual performance degradation (aging) are the result of complex interrelated phenomena that depend on battery chemistry, design, environment, and the actual operation conditions.
Such reactions reduce stability and create safety concerns as they can cause catastrophic internal battery failure leading to uncontrollable reactions and thermal runaway that can cause batteries to rupture, ignite, or explode.
This capacity fade phenomenon is the result of various degradation mechanisms within the battery, such as chemical side reactions or loss of conductivity , . On the other hand, lithium-ion batteries also experience catastrophic failures that can occur suddenly.
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.
