Title: What is the Role of Nb in Nickel-Rich Layered Oxide Cathodes for Lithium-Ion Batteries?

Abstract

Nickel-rich layered metal oxide LiNi_1–y–zMn_yCo_zO₂ (1 – y – z ≥ 0.8) materials are the most promising cathodes for next-generation lithium-ion batteries in electric vehicles. However, they lose more than 10% of their capacity on the first cycle, and interfacial/structural instability causes capacity fading. Coating and substitution are possible direct and effective solutions to solve these challenges. In this Letter, Nb coating and Nb substitution on LiNi_0.8Mn_0.1Co_0.1O₂ (NMC811) is easily produced through a scalable wet chemistry method followed by sintering from 400 to 800 °C. A Li-free Nb oxide treatment is found to remove surface impurities forming a LiNbO₃/Li₃NbO₄ surface coating, to reduce the first capacity loss and to improve the rate performance. Furthermore, Nb substitution stabilizes the structure, as evidenced by less heat evolution on heating, thus providing better long cycling stability with a 93.2% capacity retention after 250 cycles.

Electrochemical Characterization and Microstructure Evolution of Ni-Rich Layered Cathode Materials by Niobium Coating/Substitution

Journal Article Xin, Fengxia ; Goel, Anshika ; Chen, Xiaobo ; ... - Chemistry of Materials

The high nickel layered mixed metal oxides, such as LiNi_zCo_yMn_{1–z–y–q}Al_qO₂, are the most utilized cathode materials in Li-ion batteries for electric vehicles due to their high energy density. However, as the nickel content increases, they suffer from poor capacity retention and from voltage fading due to interfacial/ structural instability. In this paper, a series of Nb-coated/substituted LiNi_0.9Co_0.05Mn_0.05O₂ (NMC 9055) were synthesized by reacting the Nb precursors, Ni_0.9Co_0.05Mn_0.05(OH)₂, and LiOH. Nb is found in the NMC structure and also on the grain boundaries between the primary particles. These Nb-modified materials showed improved capacity retention and charge/discharge voltage profiles over the untreatedmore »« less

Unveiling the Role of Al₂O₃ in Preventing Surface Reconstruction During High-Voltage Cycling of Lithium-Ion Batteries

Journal Article David, Lamuel ; Dahlberg, Kevin ; Mohanty, Debasish ; ... - ACS Applied Energy Materials

Recent achievements in high-energy batteries have been made by using Ni-rich NMC cathodes (LiNi_xMn_yCo_1–x–yO ₂with x > 0.5) in conjunction with higher cell voltages. However, these gains have come at a cost of fast capacity fade and poor rate performace. In our previous study, we showed that Al₂O₃ ALD coatings on LiNi_0.8Mn_0.1Co_0.1O₂ (NMC811) and LiNi_0.8Co_0.15Al_0.05O₂ (NCA) cathodes prevented surface phase transitions, reduced impedance, and extended cycle life in high voltage cells. In this work, neutron diffraction (ND), X-ray photoelectron spectroscopy (XPS), and electron energy loss spectroscopy (EELS) are used to fully investigate the mechanism by which ALD surface coatings mitigatemore »« less

From Coating to Dopant: How the Transition Metal Composition Affects Alumina Coatings on Ni-Rich Cathodes

Journal Article Han, Binghong ; Key, Baris ; Lapidus, Saul H. ; ... - ACS Applied Materials and Interfaces

Surface alumina coatings have been shown to be an effective way to improve the stability and cyclability of cathode materials. However, a detailed understanding of the relationship between the surface coatings and the bulk layered oxides is needed to better define the critical cathode–electrolyte interface. In this work, we systematically studied the effect of the composition of Ni-rich LiNi_xMn_yCo_1–x–yO₂ (NMC) on the surface alumina coatings. Changing cathode composition from LiNi_0.5Mn_0.3Co_0.2O₂ (NMC532) to LiNi_0.6Mn_0.2Co_0.2O₂ (NMC622) and LiNi_0.8Mn_0.1Co_0.1O₂ (NMC811) was found to facilitate the diffusion of surface alumina into the bulk after high-temperature annealing. By use of a variety of spectroscopic techniques,more »« less

Degradation in Ni-Rich LiNi_1–x–yMn_xCo_yO₂/Graphite Batteries: Impact of Charge Voltage and Ni Content

Journal Article West, Patrick J. ; Quilty, Calvin D. ; Wang, Zhongling ; ... - Journal of Physical Chemistry. C

Ni-rich LiNi_1–x–yMn_xCoyO₂ (NMC) materials are attractive as cathodes for Li-ion batteries due to their high energy density and low Co content. However, these materials may display poor electrochemical reversibility relating to structural and interfacial instabilities. The influence of Ni content and level of delithiation during charge on degradation mechanisms and relevance to electrochemical cycling behavior are probed for LiNi_0.6Mn_0.2Co_0.2O₂ (NMC622) and LiNi_0.8Mn_0.1Co_0.1O₂ (NMC811) cathode materials in a full cell configuration under two upper voltage limits (4.1 and 4.3 V). The combined use of dQ/dV analysis of electrochemical voltage profiles, operando XRD, and postcycling scanning electron microscopy (SEM) measurements indicates that a major contributor to capacity fade is the large anisotropic volume change from an H2more »« less

High-performance LiNi_0.8Mn_0.1Co_0.1O₂ cathode by nanoscale lithium sulfide coating via atomic layer deposition

Journal Article Wang, Xin ; Cai, Jiyu ; Ren, Yang ; ... - Journal of Energy Chemistry

The commercialization of nickel-rich LiNi_0.8Mn_0.1Co_0.1O₂ (NMC811) has been hindered by its continuous loss of practical capacity and reduction in average working voltage. To address these issues, surface modification has been well-recognized as an effective strategy. Different from the coatings reported in literature to date, in this work, we for the first time report a sulfide coating, amorphous Li₂S via atomic layer deposition (ALD). Here, our study revealed that the conformal nano-Li₂S coating shows exceptional protection over the NMC811 cathodes, accounting for the dramatically boosted capacity retention from ~11.6% to ~71% and the evidently mitigated voltage reduction from 0.39 to 0.18more »« less
