Stress‐Induced Anomalous Lithiation Plateau of LiFe<i><sub>y</sub></i>Mn<sub>1−</sub><i><sub>y</sub></i>PO<sub>4</sub> Over High‐Rate Discharging (Adv. Energy Mater. 10/2025)
Cathode Materials In article number 2404929, Kaipeng Wu and co-workers demonstrate that the anomalous lithiation plateau of LiFeyMn1−yPO4 originates from stress concentration occurring at the interface between particle surface and bulk during rapid lithium insertion. This stress alleviates the lattice distortion of MnO6 octahedra, thereby enhancing the Li+ diffusion kinetics and eventually unlocking the capacity of Mn3+.
