    <jats:title>Abstract</jats:title><jats:p>The high‐voltage spinel lithium nickel manganese oxide (LNMO) with an operating voltage of 4.8 V is a promising cathode material for next‐generation lithium‐ion batteries (LIBs). However, LNMO/graphite (LNMO/Gr) full cells suffer capacity fading, which limits their practical applications. In this study, lithium metaborate (LBO) is applied on the LNMO surface to improve the full cell performance via a dry mixing method. The LBO‐coated LNMO delivers much better cycling stability than the uncoated LNMO in full cells with a practical 3 mAh cm<jats:sup>−2</jats:sup> areal capacity. Different characterizations are performed to understand the coating effect to track the boron and its impact on the cathode, electrolyte, and anode. The LBO‐coated LNMO owns a 5 nm cathode electrolyte interphase (CEI) with mitigated phase change after long‐term cycling. The uncoated LNMO has negligible CEI with obvious phase change. However, no boron can be detected on the surface of the coated sample. Electrolyte and anode analyses indicate that the coating acts as an additive reservoir, gradually dissolves into the electrolyte, and generates BF<jats:sub>4</jats:sub><jats:sup>−</jats:sup> species. As a result, Nickel/Manganese (Ni/Mn) dissolution from LNMO and the extensive generation of solid electrolyte interphase (SEI) on the anode side is mitigated, thus improving the full‐cell cycling stability to a great extent.</jats:p>

A variety of electrolyte additives and additive combinations were tested in the LNMA cells. The best performing electrolyte in high voltage LNMA cells (4.6 V upper cut-off) was Control + 2% fluoroethylene carbonate (FEC) + 1% lithium difluorophosphate (LFO) + 1% lithium difluoro(oxalato)borate (LiDFOB) with 87% capacity retention after 720 cycles. LNMA cells cycled to 4.25 V and LNMC cells cycled to 4.44 V at 40 °C were able to cycle for 1000 cycles before reaching 80% capacity. These materials can have surprisingly good high-voltage performance, but we stress that a fundamental breakthrough that can eliminate the voltage fade that is ubiquitous in Li-rich and Mn-rich materials is necessary to make Li-rich materials competitive with existing cell chemistries. We demonstrate that the high specific capacity of Li-rich materials can be deceptive when making conclusions about the energy density of Li-rich/graphite full cells. Hopefully, these results can set a baseline for other researchers in the Li-rich space.</jats:p>

    <jats:title>Abstract</jats:title><jats:p>Lithium‐rich layered oxides (LRLO) have attracted great interest for high‐energy Li‐ion batteries due to their high theoretical capacity. However, capacity decay and voltage fade during the cycling impede the practical application of LRLO. Herein, the use of lithium bis‐(oxalate)borate (LiBOB) as an electrolyte additive is reported to improve the cycling stability in high voltage LRLO/graphite full cells. The cell with LiBOB‐containing electrolyte delivers 248 mAh g<jats:sup>−1</jats:sup> initial capacity and shows no capacity decay after 70 cycles as well as 95.5% retention after 150 cycles over 4.5 V cycling. A systematic mechanism study for the LiBOB‐enabled cycling performance improvement is conducted. Analytical electron microscopy under cryo‐condition confirms the formation of a uniform interphase and less phase transformation on the LRLO particle, accompanied by less voltage decay in the cathode. The formation of B‐F species is identified in the cycled electrolyte, elucidating the HF scavenger effect of LiBOB. Due to less HF corrosion on both electrode interphases, a reduced amount of transition metal dissolution and redeposition on the graphite is proved, thereby mitigating the capacity decay in LRLO/graphite full cells. These findings suggest that the borate additive is a promising strategy to optimize high voltage electrolyte for the industrialization of LRLO.</jats:p>

    <jats:p>Ni-rich positive electrode materials for Li-ion batteries have the dual benefit of achieving high energy density while reducing the amount of Co used in cells. However, limitations in cycle life are still an issue for the widespread adoption of these materials. The benefit of using single crystal materials has been demonstrated for LiNi<jats:sub>0.5</jats:sub>Mn<jats:sub>0.3</jats:sub>Co<jats:sub>0.2</jats:sub>O<jats:sub>2</jats:sub> (NMC532), LiNi<jats:sub>0.6</jats:sub>Mn<jats:sub>0.2</jats:sub>Co<jats:sub>0.2</jats:sub>O<jats:sub>2</jats:sub> (NMC622), and now LiNi<jats:sub>0.8</jats:sub>Mn<jats:sub>0.1</jats:sub>Co<jats:sub>0.1</jats:sub>O<jats:sub>2</jats:sub> (NMC811). This work uses long-term cycling, ultra-high precision coulometry (UHPC), and isothermal microcalorimetry to investigate the effect of particle morphology on the lifetime of NMC811/graphite pouch cells. NMC811 with uncoated single crystal (SC) particles, coated polycrystalline (PC) particles, and a composite “bimodal” (BM) material are studied with electrolyte systems that have shown excellent cycle life in other NMC materials. Results from this work show that SC cells have improved cycle life in long-term cycling, as well as higher coulombic efficiency (CE) and lower charge endpoint capacity slippage as seen in the UHPC measurements. This correlates well with the isothermal microcalorimetry results, in which SC cells show the lowest parasitic heat flow over a range of upper-cutoff voltages. This study suggests excellent lifetimes can be achieved in single crystal NMC811/graphite cells with further electrolyte optimization.</jats:p>
