Fig. 6. Solvent effect on anode performance (solvent = carboxylate (MA, EA, NPA) or carbonate (DMC, EMC, DEC). Representative SOA electrolyte: 1 M NaPF6-EC/DEC 1 : 1 by volume). Discharge/charge rate: 0.1C. (a) Charging and discharging profiles of the 2nd cycle; (b) specific discharge capacity; (c) EIS curve of each cell after the 5th cycle; (d) Rohm and Rint after the 5th cycle; (e) CE (top) and capacity (bottom) with cycling; (f) ICE and average CE (21st–30th); (g and h) SEI component analyzed by XPS.
