SEM and TEM images of electrodes: (a) Photographs of free standing mSi@GNG films. (b) Focused Ion Beam (FIB) image of mSi@GNG sample at 52°. (c,d) SEM images of the mSi@GNG film. (e) Photographs of mSi@NG films after 80 cycles. (f,h) SEM images of mSi@GNG and mSi electrode after 80 cycles, respectively. (g) FIB-prepared cross section image of mSi@GNG. The Pt coating was deposited to protect the mSi@GNG from ion bombard damage. (i) TEM image made by FIB cutting of mSi@GNG electrode after cycles, scale bar: 1 μm. (j) Corresponding elements mapping of Si (yellow), O (red) and C (white). (k–m) element mapping of Si, O, C, respectively.
