Figure 5.
In situ secondary and backscattered electron images of a Si thin flake anode during (a) the 2nd discharge and (b) the 3rd charge processes. The charge/discharge process was conducted in constant current and constant voltage (CC/CV) mode with cut-off voltages ranging between −3.88 V and −2.40 V (vs. LiCoO2). The CC rates for the charge and discharge processes were 0.5 C.
