Back cover image : Rare‐earth sulfides are of research interest for lithium‐ion batteries (LIBs) due to their abundant lithium intercalation sites and low redox voltage. However, their electrochemical performances are not satisfactory because of poor conductivity and volume change upon electrochemical cycling. In article number 10.1002/cey2.130 , research teams by Jipeng Fu and Mingxue Tang collaborated to develop Stöber sol‐gel method and in‐shell sulfuration method, by which craft γ‐Ce 2 S 3 nanoparticles in hollow mesoporous carbon shell with tunable voids to buffer the volume change upon electrochemical cycling. The synergetic effects of nanosized Ce 2 S 3 core and the coating carbon shell offer enhanced rate performance and cycle specific capacitance. The working mechanism is unraveled with ex‐situ XRD and NMR characterizing techniques.
