Abstract

Abstract : The Cover Feature illustrates the combined sodium intercalation and copper extrusion mechanism occurring during the discharge process of CuCrP2 S6 anodes in sodium‐ion batteries. Initially, Na + ions intercalate into the van der Waals gaps of CuCrP2 S6 and Cu + ions are expelled followed by reduction to elemental Cu. During this initial process the crystallinity of the host structure is mainly maintained, but an expansion of the interlayer space is observed.
