However, the complex nature of mechanical degradation in batteries often involves interrelated processes, in which different failure mechanisms interact and evolve.
In conclusion, addressing mechanical failures in LIBs is crucial for making significant advancements in battery performance, lifetime, and safety, as well as for advancing next-generation battery technologies.
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.
Mechanical failures in LIBs manifest across various scales, including the particle scale, electrode scale, and cell scale. Failure behaviors such as particle fragmentation, active layer cracking, electrode delamination, and battery deformation can coexist and simultaneously impact battery performance, lifetime, and safety.
Extensive research has demonstrated that mechanical failures play a crucial role in determining battery performance, lifespan, and safety [1, 2]. LIBs are intricate and dynamic systems with continuously evolving composition, structure, and properties .
