Title: A review of recent research on nonequilibrium solid solution behavior in Li_XFePO₄ [A review of nonequilibrium solid solution in Li_XFePO₄]

Abstract

Li_XFePO₄ (0 < X < 1) is one of the most well-studied cathode battery materials and is notable for its large miscibility gap. Although its phase-separating behaviors under equilibrium conditions have been well documented, recent research has shown that phase separation is suppressed at elevated rates of lithium insertion and removal. Specifically, Li_XFePO₄ exhibits a nonequilibrium solid solution behavior at elevated cycling rates. This article reviews recent research on nonequilibrium solid solution in Li_XFePO₄; these insights have been largely enabled by operando characterization techniques. As a result, such studies have not only unambiguously confirmed the existence of this solid solution, but also show how surface reaction and diffusion kinetics ultimately affect phase separation and other spatially nonuniform lithiation and delithiation behavior.

Nanoscale Detection of Intermediate Solid Solutions in Equilibrated Li_xFePO₄ Microcrystals

Journal Article May, Brian M. ; Yu, Young-Sang ; Holt, Martin V. ; ... - Nano Letters

Redox-driven phase transformations in solids determine the performance of lithium-ion batteries, crucial in the technological transition from fossil fuels. Couplings between chemistry and strain define reversibility and fatigue of an electrode. The accurate definition of all phases in the transformation, their energetics, and nanoscale location within a particle produces fundamental understanding of these couplings needed to design materials with ultimate performance. In this paper we demonstrate that scanning X-ray diffraction microscopy (SXDM) extends our ability to image battery processes in single particles. In LiFePO₄ crystals equilibrated after delithiation, SXDM revealed the existence of domains of miscibility between LiFePO₄ and Li_0.6FePO₄.more »« less

Phase-field modeling of diffusional phase behaviors of solid surfaces: A case study of phase-separating Li_XFePO₄ electrode particles

Journal Article Heo, Tae Wook ; Chen, Long-Qing ; Wood, Brandon C. - Computational Materials Science

In this paper, we present a comprehensive phase-field model for simulating diffusion-mediated kinetic phase behaviors near the surface of a solid particle. The model incorporates elastic inhomogeneity and anisotropy, diffusion mobility anisotropy, interfacial energy anisotropy, and Cahn–Hilliard diffusion kinetics. The free energy density function is formulated based on the regular solution model taking into account the possible solute-surface interaction near the surface. The coherency strain energy is computed using the Fourier-spectral iterative-perturbation method due to the strong elastic inhomogeneity with a zero surface traction boundary condition. Employing a phase-separating Li_XFePO₄ electrode particle for Li-ion batteries as a model system, wemore »« less

Revealing Insights into Li_xFePO ₄ Nanocrystals with Magnetic Order at Room Temperature Resulting in Trapping of Li Ions

Journal Article Hu, Jiangtao ; Zeng, Hua ; Chen, Xin ; ... - Journal of Physical Chemistry Letters

A systematic report on the structures, magnetic properties, and electrochemical performance of Li_xFePO₄ was carried out. Interestingly, it was discovered that the magnetic phase transition temperature is around 295 K in Li_xFePO₄ (x ≤ 0.12) nanocrystals, which is higher than that of LiFePO₄ (T_N = 51(1) K) and FePO₄ (TN = 114(1) K) phases. The origin of magnetic order around room temperature (RT) in LixFePO₄ (x ≤ 0.12) is proposed to be due to both Fe²⁺–Fe³⁺ superexchange and the broken local symmetries induced by Fe²⁺–Li⁺ antisite defects. Ab initio calculations were adopted to calculate the total energy change of themore »« less

A study of room-temperature Li_xMn_1.5Ni_0.5O₄ solid solutions

Journal Article Saravanan, Kuppan ; Jarry, Angelique ; Kostecki, Robert ; ... - Scientific Reports

Understanding the kinetic implication of solid-solution vs. biphasic reaction pathways is critical for the development of advanced intercalation electrode materials. Yet this has been a long-standing challenge in materials science due to the elusive metastable nature of solid solution phases. The present study reports the synthesis, isolation, and characterization of room-temperature Li_xMn_1.5Ni_0.5O₄ solid solutions. In situ XRD studies performed on pristine and chemically-delithiated, micron-sized single crystals reveal the thermal behavior of Li_xMn_1.5Ni_0.5O₄ (0 ≤ x ≤ 1) cathode material consisting of three cubic phases: LiMn_1.5Ni_0.5O₄ (Phase I), Li_0.5Mn_1.5Ni_0.5O₄ (Phase II) and Mn_1.5Ni_0.5O₄ (Phase III).

Dependence on Crystal Size of the Nanoscale Chemical Phase Distribution and Fracture in Li _x FePO ₄

Journal Article Yu, Young-Sang ; Kim, Chunjoong ; Shapiro, David A. ; ... - Nano Letters

The performance of battery electrode materials is strongly affected by inefficiencies in utilization kinetics and cycle life as well as size effects. Observations of phase transformations in these materials with high chemical and spatial resolution can elucidate the relationship between chemical processes and mechanical degradation. Soft X-ray ptychographic microscopy combined with X-ray absorption spectroscopy and electron microscopy creates a powerful suite of tools that we use to assess the chemical and morphological changes in lithium iron phosphate (LiFePO₄) micro- and nanocrystals that occur upon delithiation. All sizes of partly delithiated crystals were found to contain two phases with a complexmore »« less
