The Nonsteady‐State Structural and Chemical Reconstruction of Ni‐Rich Cathodes During the Intermittent Resting after Charging (Adv. Energy Mater. 23/2025)

Lithium-Ion Batteries

In article number 2405907, Chongheng Shen, Kai Wu, Minggao Ouyang, Xiang Liu, and co-workers delve into the degradation of Ni-rich cathode materials, essential for lithium-ion batteries. It centers on how short rest periods after full charge impact the material's structure. The research indicates these periods lead to structural changes. A key focus is the examination of how multi-scale heterogeneity and limited lithium-ion transport kinetics combine to accelerate this structural degradation process.
