ICP-MS analysis of cycled a electrolyte and b LMA after 100 cycles at 60 °C, the charging/discharging current were 180 mA g−1/180 mA g−1, the cell was disassembled at fully discharged state. ICP-MS analysis of c electrolyte and d LMA after rest at open circuit voltage for 7 days at 60 °C. e HF concentration of BE, BE + 1000 ppm H2O and BE + 0.6 wt% LiHMDS + 1000 ppm H2O. f H2O concentration of BE, BE + 0.6 wt% LiHMDS, BE + 1000 ppm H2O and BE + 0.6 wt% LiHMDS + 1000 ppm H2O. 19F NMR spectra of the solution of g BE + 1000 ppm H2O, h BE + 1000 ppm + 0.6 wt% LiHMDS and i BE + 0.6 wt% LiHMDS + 1000 ppm H2O.
