Abstract The ionic liquid (IL)\u2010based electrolyte comprising 1.2 M lithium bis(fluorosulfonyl)imide (LiFSI) in N\u2010propyl\u2010N\u2010methylpyrrolidinium bis(fluorosulfonyl)imide (PYR 13 FSI) (ILE) has been evaluated as a suitable system for the high\u2010voltage cathode material LiNi 0.5\u2212 x Mn 1.5+ x O 4 (LNMO) when cycled vs. graphite anodes. The oxidative stability of the ILE was evaluated by linear sweep voltammetry (LSV) and synthetic charge\u2010discharge profile voltammetry (SCPV) and was found to exceed that of state\u2010of\u2010the\u2010art 1 M LiPF 6 in 1 : 1 ethylene carbonate (EC) : diethylcarbonate (DEC) (LP40). Improved cycling performance both at 20 \u00b0C and 45 \u00b0C was found for LNMO||graphite full cells with the IL electrolyte. X\u2010ray photoelectron spectroscopy (XPS) analysis showed that robust and predominantly inorganic surface layers were formed on the LNMO cathode using the ILE, which stabilized the electrode. Although the high viscosity of the ILE limits the rate performance at 20 \u00b0C, this ILE is a promising alternative electrolyte for use in lithium\u2010ion batteries (LiBs) with high\u2010voltage cathodes such as LNMO, especially for use at elevated temperatures.<\/p>\n","protected":false},"excerpt":{"rendered":"
