Figure 2

(a) Li intercalation profiles and (b) Li de‐intercalation profiles for BF‐graphite/Li cells cycled with various concentrations of LiPF6/PC electrolytes. TEM images of fresh and cycled graphite anodes with different concentrations of LiPF6/PC electrolytes: (c) Fresh graphite, (d) 1.2 m, and (e) 3.5 m. The inset presents the element composition detected by energy‐dispersive X‐ray spectroscopy (EDX). Reproduced with permission.[[qv: 11a]] Copyright 2013 American Chemical Society.
