Detection of S species evolution during various charge-discharge stages. S 2p XPS spectra of NaCrS2 samples, a pristine, b after charging to 3.0 V, and c after discharging to 1.5 V. Crystal structures and electron density contours of d pristine NaCrS2 and e Na0.5CrS2 with 1/6 Cr/V′Na antisite (2 × 2 × 1 conventional cells). Selected planes are through the Cr and S ions labeled in crystal structures. The contour unit is e/Bohr3 (1 Bohr = 0.529 Å)
