A predominant focus lies on instances of abrupt capacity reduction attributed to localized, conspicuous deformations in cylindrical batteries.
A predominant focus lies on instances of abrupt capacity reduction attributed to localized, conspicuous deformations in cylindrical batteries. Only a few studies have focused on the evolution of capacity degradation trajectories after minor deformation damage in batteries, and the underlying degradation mechanisms have not been fully elucidated.
Based on the transient and progressive degradation behaviors of batteries, the mechanical deformation damage of batteries is classified into three levels, and quantitative damage degree thresholds are established.
npj Materials Degradation 8, Article number: 43 (2024) Cite this article State-of-the-art lithium-ion batteries inevitably suffer from electrode corrosion over long-term operation, such as corrosion of Al current collectors. However, the understanding of Al corrosion and its impacts on the battery performances have not been evaluated in detail.
The most studied battery types in terms of their component corrosion and degradation are MIBs and MABs, followed by redox-flow, lead-acid and metal-hydride batteries. Among the MIBs, the maximum investigated type of corrosion is the corrosion of current collectors. In MABs, most works focused on anode corrosion.
During the battery cycling, the passivation layer greater than 20 nm was generated near the median voltage. When the charging voltage rose, the passivation layer was squeezed and deformed by the newly generated Al-F-O particles, resulting in stress corrosion cracks.
