Table 1. CE, SEI Formation Capacity and Dead Li Capacity in the First Cycle Calculated Using the Dead Li_NMR Intensity Determined by In Situ NMR and the CE Determined from Electrochemistry^a.

electrolyte	coulombic efficiency	SEI formation capacity (mAh/cm²)	dead Li capacity (mAh/cm²)
LP30	85 ± 2%	0.09 ± 0.005	0.06 ± 0.02
LP30 + FEC	90 ± 1%	0.09 ± 0.01	0.01 ± 0.001
DOL/DME	75 ± 3%	0.16 ± 0.01	0.11 ± 0.03

The standard deviation is that derived from the three separate in situ NMR experiments.
