Lithium Clustering during the Lithiation/Delithiation Process in LiFePO₄ Olivine-Structured Materials.

ABSTRACT: Olivine-structured LiFePO₄ is one of the most popular cathode materials in lithium-ion batteries (LIBs) for sustainable applications. Significant attention has been paid to investigating the dynamics of the lithiation/delithiation process in Li _x FePO₄ (0 ≤ x ≤ 1), which is crucial for the development of high-performance LiFePO₄ material. Various macroscopic models based on experimental evidence have been proposed to explain the mechanism of phase transition from LiFePO₄ to FePO₄, such as the shrinking core (i.e., core-shell) model, Laffont's (i.e., new core-shell) model, domino-cascade model, phase transformation wave, solid solution model, many-particle models, etc. However, these models, unfortunately, contr
