XAFS fitting curves at the (c) Cu L3-edge and (d) Co L3-edge for Cu7S4/Co9S8/C (k3 space). Wavelet-transform-EXAFS (WT-EXAFS) of Cu7S4/Co9S8/C at the (e) Cu L3-edge and (f) Co L3-edge. (g) In situ Raman spectra and corresponding 2D contour map during the first cycle of Cu7S4/Co9S8/C. (h) Selected XRD patterns at various discharge/charge potentials. (i) In situ XRD pattern with 2D contour map over the first cycle.
