Title: Exploring the influence of iron substitution in lithium rich layered oxides Li₂Ru_1–xFe_xO₃: triggering the anionic redox reaction

Abstract

Lithium rich layered materials are an interesting class of materials which exploit both anionic and cationic redox reactions to store energy upwards of 250 mA h g^–1. This paper aims to understand the nature of the redox reactions taking place in these compounds. Li₂RuO₃ was used as the base compound, which is then compared with compounds generated by partially substituting Ru with Ti and Fe respectively. Electrochemical tests indicate that Fe substitution in the sample leads to an improvement in capacity, cycle life and reduction of potential decay. To elucidate the reason for this improvement in operando diffraction experiments were carried out, highlighting the formation of a secondary de-lithiated phase. The distortion of the pristine structure eventually induces frontier orbital reorganization leading to the oxygen redox reaction resulting in extra capacity. Local changes at Fe and Ru ions are recorded using in operando X-ray absorption spectroscopy (XAS). It was noted that while Ru undergoes a reversible redox reaction, Fe undergoes a significant irreversible change in its coordination environment during cycling. In conclusion, the changes in the coordination environment of oxygen and formation of O₂^n– type species were probed in situ using soft X-rays.

Access to Ru(IV)–Ru(V) and Ru(V)–Ru(VI) Redox in Layered Li₇RuO₆ via Intercalation Reactions

Journal Article Li, Haifeng ; Taudul, Beata ; Alexander, Grant C. B. ; ... - Chemistry of Materials

The push to increase the capacity of oxides to store charge as Li-ion battery cathodes has challenged our knowledge of the boundaries of redox chemistry and its relationship to the atomic structure. Layered phases with Ru are now classical models in the quest for refined theories. Current understanding dictates that the highest formal state that can be reached in them is Ru(V), after which activity centered at the oxide anions is triggered. Yet, this picture is challenged by this investigation of the intercalation chemistry of Li₇RuO₆. Coupling structural and spectroscopic analysis with computational simulations, we show that Li₇RuO₆ is capablemore »« less

Definition of Redox Centers in Reactions of Lithium Intercalation in Li₃RuO₄ Polymorphs

Journal Article Li, Haifeng ; Ramakrishnan, Srinivasan ; Freeland, John W. ; ... - Journal of the American Chemical Society

Cathodes based on layered LiMO₂ are the limiting components in the path toward Li-ion batteries with energy densities suitable for electric vehicles. Introducing an over-stoichiometry of Li increases storage capacity beyond a conventional mechanism of formal transition metal redox. However, the role and fate of the oxide ligands in such intriguing additional capacity remain unclear. This reactivity was predicted in Li₃RuO₄, making it a valuable model system. For this study, a comprehensive analysis of the redox activity of both Ru and O under different electrochemical conditions was carried out, and the effect of Li/Ru ordering was evaluated. Li₃RuO₄ displays highlymore »« less

Structural and magnetic properties of Pr{sub 18}Li{sub 8}Fe{sub 5-x}M{sub x}O{sub 39} (M=Ru, Mn, Co)

Journal Article Dutton, Sian E ; Battle, Peter D., E-mail: Peter.Battle@chem.ox.ac.u ; Grandjean, Fernande ; ... - Journal of Solid State Chemistry

A polycrystalline sample of Pr{sub 18}Li{sub 8}Fe{sub 4}RuO{sub 39} has been synthesized by a solid state method and characterized by neutron powder diffraction, magnetometry and Moessbauer spectroscopy; samples of Pr{sub 18}Li{sub 8}Fe{sub 5-x}Mn{sub x}O{sub 39} and Pr{sub 18}Li{sub 8}Fe{sub 5-x}Co{sub x}O{sub 39} (x=1, 2) have been studied by magnetometry. All these compounds adopt a cubic structure (space group Pm3-barn, a{sub 0}{approx}11.97 A) based on intersecting <111> chains made up of alternating octahedral and trigonal-prismatic coordination sites. These chains occupy channels within a Pr-O framework. The trigonal-prismatic site in Pr{sub 18}Li{sub 8}Fe{sub 4}RuO{sub 39} is occupied by Li{sup +} and high-spinmore »« less

Novel Ordered Rocksalt-Type Lithium-Rich Li₂Ru_1–xNi_xO_3-δ (0.3 ≤ x ≤ 0.5) Cathode Material with Tunable Anionic Redox Potential

Journal Article Zheng, Shiyao ; Zheng, Feng ; Liu, Haodong ; ... - ACS Applied Energy Materials

In this work, a series of ordered rocksalt (OR) type Li-rich Li₂Ru_1–xNi_xO_3-δ (LRN_xO, 0.3 ≤ x ≤ 0.5) are successfully synthesized and investigated for the first time. X-ray diffraction and neutron powder diffraction patterns exhibit an obvious phase transition from layered to an OR structure as the Ni content gradually increases from x = 0 to x = 0.5, which leads to different electrochemical behaviors. In the case of OR-LRN_0.4O, an ~350 mV decrease of the oxygen oxidation potential compared with Li₂RuO₃ (LRO) is observed from around 4.2 to 3.85 V, which is confirmed by both X-ray photelectron O 1smore »« less

Exploring the Origin of Anionic Redox Activity in Super Li-Rich Iron Oxide-Based High-Energy-Density Cathode Materials

Journal Article Yao, Zhenpeng ; Chan, Maria Y. ; Wolverton, Chris - Chemistry of Materials

Super alkali-rich materials (alkali:transition metal ratio of ≥2:1), such as Li₅FeO₄, exhibit the potential to realize anionic redox upon deep delithiation. Li₅FeO₄ was shown to undergo reversible cycling between Li₄FeO_3.5 and Li₃FeO_3.5 with combined cation/anion redox, a remarkable capacity of 189 mAh/g, and no O₂ release. However, the impact of phase transformations on the reaction thermodynamics and the correlation between the structural changes and reaction reversibility remain unclear. In this study, we use first-principles calculations to examine the delithiation and (re)lithiation reactions of Li₅FeO₄. We show that the experimentally observed charge and discharge processes go through non-equilibrium pathways. Upon delithiation,more »« less
