Figure 3

XRD patterns are shown for various lithiation times. (a) The CZTSSe 112 reflex is shown as a zoom-in. Semitransparent lines mark the XRD pattern before the treatment. (b) A zoom-in to the CZTSSe 400 and 008 reflexes is shown. Semi-transparent lines mark the XRD pattern before the treatment. (c) The difference in lattice parameter is calculated from the respective values obtained from peak deconvolution of XRD patterns before and after electrochemical treatment. An increase in lithiation time results in widening of both lattice parameters, a and c.
