Title: Stabilizing Cathode Materials of Lithium-Ion Batteries by Controlling Interstitial Sites on the Surface

Abstract

Lithium-ion batteries with high energy density are being intensively pursued to meet the ever-growing demand for energy storage. However, the increase in energy density often comes with an elevated instability of electrode materials, causing major concerns about the reliability and safety of lithium-ion batteries. In this paper, we report a strategy for stabilizing cathode materials by modulating the vacant lattice sites on the particle surface. Using the high-voltage Li[Ni_0.5Mn_1.5]O₄ as an example, we demonstrate that introduction of a 10-nm epitaxial surface layer with Al³⁺ in the empty 16c octahedral sites of the spinel Li[Ni_0.5Mn_1.5]O₄ suppresses structural degradation during cycling by increasing the surface stability without interfering with the Li⁺ diffusion around the Al³⁺ sites. Control of the Al³⁺ concentration in the surface region was shown to be a facile process. Finally, the process was shown to stabilize long-term cycling of Li[Ni_0.5Mn_1.5]O₄ to 5 V versus Li⁺/Li⁰.

Insight into the Atomic Structure of High-Voltage Spinel LiNi_0.5Mn_1.5O4 Cathode Material in the First Cycle

Journal Article Huang, Xuejie ; Yu, Xiqian ; Lin, Mingxiang ; ... - Chemistry of Materials

Application of high-voltage spinel LiNi_0.5Mn_1.5O4 cathode material is the closest and the most realistic approach to meeting the midterm goal of lithium-ion batteries for electric vehicles (EVs) and plug-in hybrid electric vehicles (HEVs). However, this application has been hampered by long-standing issues, such as capacity degradation and poor first-cycle Coulombic efficiency of LiNi_0.5Mn_1.5O4 cathode material. Although it is well-known that the structure of LiNi_0.5Mn_1.5O4 into which Li ions are reversibly intercalated plays a critical role in the above issues, performance degradation related to structural changes, particularly in the first cycle, are not fully understood. Here, we report detailed investigations ofmore »« less

Composition-structure-property-performance relationship inMn-substituted LiMn2O4

Conference Horne, Craig R ; Richardson, Thomas J ; Gee, B ; ...

The spinel LiMn{sub 2}O{sub 4} has been extensively studied as a positive electrode active material in lithium rechargeable batteries. Partial substitution of Mn by another metal has also been the subject of recent study in an effort to improve the cycling performance. In general, the literature has shown that Mn substitution results in improved cycling stability at the expense of capacity (1,2). Resistance to the formation of tetragonal phase upon lithiation of the starting spinel (via a higher nominal Mn oxidation state in the substituted spinel) has been suggested as a mechanism for the improved performance. The degree of substitutionmore »« less

Interfacial engineering for stabilizing polymer electrolytes with 4V cathodes in lithium metal batteries at elevated temperature

Journal Article Li, Zeyuan ; Li, Aijun ; Zhang, Hanrui ; ... - Nano Energy

Poly (ethylene oxide) (PEO) polymer electrolytes are promising candidates for next-generation rechargeable lithium batteries. However, the poor interfacial stability between 4 V cathodes and PEO electrolytes impedes their applications in 4 V lithium batteries with high energy density. Here, we demonstrate a facile and effective strategy to enhance the interfacial stability by the synergy of Li_1.5Al_0.5Ge_1.5(PO₄)₃ (LAGP) coating on the cathode surface, and salt combination in the electrolyte, even with a cut-off voltage of 4.25–4.4 V vs. Li⁺/Li. Nano-LAGP coated Li|PEO|LiCoO₂ cell delivers stable cycling with a capacity retention of 81.9%/400 cycles and 84.7%/200 cycles at 60 °C when chargedmore »« less

Visualizing nanoscale 3D compositional fluctuation of lithium in advanced lithium-ion battery cathodes

Journal Article Devaraj, Arun ; Gu, Meng ; Colby, Robert J. ; ... - Nature Communications

The distribution and concentration of lithium in Li-ion battery cathodes at different stages of cycling is a pivotal factor in determining battery performance. Non-uniform distribution of the transition metal cations has been shown to affect cathode performance; however, the Li is notoriously challenging to characterize with typical high-spatial-resolution imaging techniques. Here, for the first time, laser–assisted atom probe tomography is applied to two advanced Li-ion battery oxide cathode materials—layered Li_1.2Ni_0.2Mn_0.6O₂ and spinel LiNi_0.5Mn_1.5O₄—to unambiguously map the three dimensional (3D) distribution of Li at sub-nanometer spatial resolution and correlate it with the distribution of the transition metal cations (M) and themore »« less

Energetics of Lithium Insertion into Magnetite, Defective Magnetite, and Maghemite

Journal Article Lininger, Christianna N. ; Cama, Christina A. ; Takeuchi, Kenneth J. ; ... - Chemistry of Materials

At low concentrations of lithium insertion into inverse spinel magnetite Fe₃O₄, a phase change to rock-salt-like Li_xFe₃O₄ has been observed. Here, we used density-functional-theory-based (DFT-based) calculations to study the structural origins of this phase change, the concentration at which it occurs, the role of iron vacancies, and the stability of the various motifs that form during the electrochemical reduction process in the Li–Fe–O ternary space up to x = 1.33. We compared our results to new experimental measurements of the open circuit voltage for 8–9 nm magnetite particles over a comparable range of lithium insertion. Of the vacant sites inmore »« less
