Fig. 1 Spontaneous co-intercalation of Cu and ether into NbS2. (a) and (b) XRD patterns and Rietveld refinement of NbS2 and Cux(DME)nNbS2. The inset shows HRTEM images of NbS2 and Cux(DME)nNbS2. (c) XANES at the Cu K-edge for Cux(DME)nNbS2 and corresponding reference samples. (d) FTIR spectrum of the NbS2 electrode after assembly into half cells with different electrolytes. (e) HAADF-STEM image of Cux(DME)nNbS2 along a/b-axes. The inset on the right shows the atom intensity profiles. (f) Schematic illustration.
