| Abstract | Seleniumesulfur solid solutions show unique advantages beyond sulfur and selenium as cathode materials for lithium batteries. Herein, we propose a dual-confined SexSy-based cathode with a three-dimensional (3D) network structure where Se0.4S0.6 is first encapsulated in double-layered hollow carbon spheres (DLHCs) and embedded by 3D graphene-like material (3DG) shells. The dissolution of polysulfides/ polyselenides in the cathode is effectively inhibited through dual confinement from DLHCs and 3DG as well as chemical binding between sulfur and selenium. Benefiting from the indispensable advantages of Se0.4S0.6 and the uniquely designed host architecture, the 3DG-DLHC-Se0.4S0.6 cathode delivers a high reversible capacity of 627 mAh g(-1) at 0.2 A g(-1) after 200 cycles, good rate capability of 533 mAh g(-1) at 2Ag(-1), and outstanding long cycling stability over 500 cycles with Coulombic efficiency almost reaching 100%.
