a Conductivity versus temperature. b Li+ transference number (t Li+) computed from DC polarization measurements at 10 mV using the Bruce–Vincent method. c Rate capability of Li | |NMC811 cells under different charging/discharging rates. d Long-term superfast charging/discharging performance of Li | |NMC811 cells using different electrolytes at 5.0 C rate. e the corresponding voltage profiles at different cycles of Li | |NMC811 cells using LiFSI–LiNO3/DME at 5.0 C rate. f Long-term cycling performances of high-voltage Li | |NMC811 full batteries with 40 μm Li anode. The N/P ratios of the Li | |NMC811 cell were 2.31. The first two formation cycles were carried out at a 0.1 C rate, followed by 15 cycles at 0.5 C rate, sequential 15 cycles at 1.0 C rate and the long-term cycling was at 2.0 C rate. g The corresponding voltage profiles of high-voltage Li | |NMC811 full batteries using LiFSI–LiNO3/DME. h Cycling performance of full cells in LiFSI–LiNO3/THF electrolyte at −40 °C and 0.3 C rate. i Discharge profiles of Li | |NMC811 cells using LiFSI–LiNO3/THF electrolyte at different temperatures.
