Structural, morphological, and electrochemical performance of NaCrS2. a XRD patterns of powder NaCrS2 (blue circle), calculated profile (black solid line), and their difference (red solid line). Bragg positions are indicated as black vertical tick marks. In the inset for the structure schematic of NaCrS2, legend: purple (Na), blue (Cr), and yellow balls (S); b HAADF-STEM image of the pristine NaCrS2 particle, scale bar 2 nm; c Galvanostatic charge/discharge curves, d cyclic performances and Coulombic efficiencies of NaCrS2 electrode at 0.5 C
