Title: Improving the Performance at Elevated Temperature of High Voltage Graphite/LiNi _0.5Mn _1.5O ₄ Cells with Added Lithium Catechol Dimethyl Borate

Performance of LiNi _0.5Mn _1.5O ₄/graphite cells cycled to 4.8 V at 55°C with the 1.2 M LiPF ₆ in EC/EMC (3/7, STD electrolyte) with and without added lithium catechol dimethyl borate (LiCDMB) has been investigated. The incorporation of 0.5 wt% LiCDMB to the STD electrolyte results in an improved capacity retention and coulombic efficiency upon cycling at 55°C. Ex-situ analysis of the electrode surfaces via a combination of SEM, TEM, and XPS reveals that oxidation of LiCDMB at high potential results in the deposition of a passivation layer on the electrode surface, preventing transition metal ion dissolution from the cathode and subsequent deposition on the anode. NMR investigations of the bulk electrolyte stored at 85°C reveals that added LiCDMB prevents the thermal decomposition of LiPF ₆.

Effect of Lithium Borate Additives on Cathode Film Formation in LiNi _0.5Mn _1.5O ₄/Li Cells

Journal Article Dong, Yingnan ; Young, Benjamin T. ; Zhang, Yuzi ; ... May 2017 - ACS Applied Materials and Interfaces

A direct comparison of the cathode–electrolyte interface (CEI) generated on high-voltage LiNi _0.5Mn _1.5O ₄ cathodes with three different lithium borate electrolyte additives, lithium bis(oxalato)borate (LiBOB), lithium 4-pyridyl trimethyl borate (LPTB), and lithium catechol dimethyl borate (LiCDMB), has been conducted. The lithium borate electrolyte additives have been previously reported to improve the capacity retention and efficiency of graphite/LiNi _0.5Mn _1.5O ₄ cells due to the formation of passivating CEI. Linear sweep voltammetry (LSV) suggests that incorporation of the lithium borates into 1.2 M LiPF ₆ in EC/EMC (3/7) electrolyte results in borate oxidation on the cathode surface at high potential.more »« less

The effect of cobalt doping on the morphology and electrochemical performance of high-voltage spinel LiNi _0.5Mn _1.5O ₄ cathode material

Journal Article Mao, Jing ; Ma, Mengze ; Liu, Panpan ; ... June 2016 - Solid State Ionics

In this paper, to reveal the effects of Co-doping on the electrochemical performance of micro-sized LiNi _0.5Mn _1.5O ₄ (LNMO), undoped LNMO and Co-doped LiCo _0.1Ni _0.45Mn _1.45O ₄ (LCoNMO) are synthesized via a PVP-combustion method and calcined at 1000 °C for 6 h. SEM and XRD analyses suggest that Co-doping decreases the particle size and the Li _zNi _1-zO ₂ impurity at the calcination temperature of 1000 °C. LCoNMO has much better rate capability while its specific capacity at C/5 is 10% lower than that of LNMO. At 15 C rate, their specific capacities are closed, and the LCoNMOmore »« less

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 ; ... December 2014 - 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.more »« less
