Abstract

he large voltage hysteresis remains one of the biggest barriers to optimizing Li/Na-ion cathodes using lattice anionic redox reaction, despite their very high energy density and relative low-cost. Very recently, a layered sodium cathode Na₂Mn₃O₇ (or Na_4/7Mn_6/7_1/7O₂, is vacancy) was reported to have reversible lattice oxygen redox with much suppressed voltage hysteresis. However, the structural and electronic structural origin of this small voltage hysteresis has not been well understood. In this article, through systematic studies using ex situ/in situ electron paramagnetic resonance and X-ray diffraction, we demonstrate that the exceptional small voltage hysteresis (< 50mV) between charge and discharge curves is rooted in the well-maintained oxygen stacking sequence in the absence of irreversible gliding of oxygen layers and cation migration from the transition metal (TM) layers. In addition, we further identify that the 4.2 V charge/discharge plateau is associated with a zero-strain (de)intercalation process of Na⁺ ions from distorted octahedral sites, while the 4.5 V plateau is linked to a reversible shrink/expansion process of the manganese-site vacancy during (de)intercalation of Na⁺ ions at distorted prismatic sites. As a result, it is expected these findings will inspire further exploration of new cathode materials that can achieve both high energy density andmore »« less

Stabilizing Transition Metal Vacancy Induced Oxygen Redox by Co²⁺/Co³⁺ Redox and Sodium-Site Doping for Layered Cathode Materials

Journal Article Li, Xun‐Lu ; Bao, Jian ; Shadike, Zulipiya ; ... - Angewandte Chemie (International Edition)

Anionic redox is an effective way to boost the energy density of layer-structured metal-oxide cathodes for rechargeable batteries. However, inherent rigid nature of the TMO₆ (TM: transition metals) subunits in the layered materials makes it hardly tolerate the inner strains induced by lattice glide, especially at high voltage. Herein, P2-Na_0.8Mg0.13[Mn_0.6Co_0.2Mg_{0.07more » $$\square$$0.13}]O₂ ($$\square$$: TM vacancy) is designed that contains vacancies in TM sites, and Mg ions in both TM and sodium sites. Vacancies make the rigid TMO₆ octahedron become more asymmetric and flexible. Low valence Co²⁺/Co³⁺ redox couple stabilizes the electronic structure, especially at the charged state. Mg²⁺ in sodium sites can tune the interlayer spacing against O-O electrostatic repulsion. Time-resolved in situ X-ray diffraction confirms that irreversible structure evolution is effectively suppressed during deep desodiation benefiting from the specific configuration. X-ray absorption spectroscopy (XAS) and density functional theory (DFT) calculations demonstrate that, deriving from the intrinsic vacancies, multiple local configurations of “_$$\square$$-O-_$$\square$$”, “Na-O-_$$\square$$”, “Mg-O-_$$\square$$” are superior in facilitating the oxygen redox for charge compensation than previously reported “Na-O-Mg”. The resulted material delivers promising cycle stability and rate capability, with a long voltage plateau at 4.2 V contributed by oxygen, and can be well maintained even at high rates. The strategy will inspire new ideas in designing highly stable cathode materials with reversible anionic redox for sodium-ion batteries.« less

Stabilizing Reversible Oxygen Redox Chemistry in Layered Oxides for Sodium‐Ion Batteries

Journal Article Cao, Xin ; Li, Haifeng ; Qiao, Yu ; ... - Advanced Energy Materials

Abstract Triggering oxygen‐related activity is demonstrated as a promising strategy to effectively boost energy density of layered cathodes for sodium‐ion batteries. However, irreversible lattice oxygen loss will induce detrimental structure distortion, resulting in voltage decay and cycle degradation. Herein, a layered structure P2‐type Na _0.66 Li _0.22 Ru _0.78 O ₂ cathode is designed, delivering reversible oxygen‐related and Ru‐based redox chemistry simultaneously. Benefiting from the combination of strong Ru 4d‐O 2p covalency and stable Li location within the transition metal layer, reversible anionic/cationic redox chemistry is achieved successfully, which is proved by systematic bulk/surface analysis by in/ex situ spectroscopy (operandomore »« less

Coulombically-stabilized oxygen hole polarons enable fully reversible oxygen redox

Journal Article Abate, Iwnetim I. ; Pemmaraju, C. Das ; Kim, Se Young ; ... - Energy & Environmental Science

Stabilizing high-valent redox couples and exotic electronic states necessitates an understanding of the stabilization mechanism. In oxides, whether they are being considered for energy storage or computing, highly oxidized oxide-anion species rehybridize to form short covalent bonds and are related to significant local structural distortions. In intercalation oxide electrodes for batteries, while such reorganization partially stabilizes oxygen redox, it also gives rise to substantial hysteresis. In this work, we investigate oxygen redox in layered Na_2-xMn₃O₇, a positive electrode material with ordered Mn vacancies. We prove that coulombic interactions between oxidized oxide-anions and the interlayer Na vacancies can disfavor rehybridization andmore »« less

Stabilizing lattice oxygen redox in layered sodium transition metal oxide through spin singlet state

Journal Article Wang, Xuelong ; Yin, Liang ; Ronne, Arthur ; ... - Nature Communications

Reversible lattice oxygen redox reactions offer the potential to enhance energy density and lower battery cathode costs. However, their widespread adoption faces obstacles like substantial voltage hysteresis and poor stability. The current research addresses these challenges by achieving a non-hysteresis, long-term stable oxygen redox reaction in the P3-type Na_2/3Cu_1/3Mn_2/3O₂. Here we show this is accomplished by forming spin singlet states during charge and discharge. Detailed analysis, including in-situ X-ray diffraction, shows highly reversible structural changes during cycling. In addition, local CuO₆ Jahn-Teller distortions persist throughout, with dynamic Cu-O bond length variations. In-situ hard X-ray absorption and ex-situ soft X-ray absorptionmore »« less

Structure and Voltage Recovery Driven by Defects Elimination in Li-Rich Layered Oxide Cathode Materials

Conference Zhang, Minghao ; Liu, Haodong ; Meng, Ying Shirley

Lithium-ion batteries (LIBs) are ubiquitous in a wide range of technologies, including cell phones, electric vehicles, and energy grid, and are indispensable in the transition toward sustainable energy technology. The battery performance is inherently connected to the capability of lithium ions to reversibly intercalate with the electrodes. The capacity of classical layered transition metal (TM) oxides, the primary commercial cathode materials, is limited to cationic redox activity. Anionic redox has thus emerged as a new paradigm for designing novel cathodes for next generation LIBs. It is recently confirmed oxygen redox in lithium-rich layered oxides (LRLO) with composition xLi₂MnO₃∙(1-x)LiTMO₂, which enablesmore »« less
