摘要	Selenium disulfide (SeS2) exhibits attractive advantages beyond naked selenium and sulfur as an electroactive material for lithium storage. Herein, a three-dimensional (3D) interconnected, sulfur-doped mesoporous carbon (ISMC) with a sulfur content of 9.3 wt% has been prepared by a simple in-situ constructing strategy to confine SeS2 for lithium batteries. The sulfur doping enhances the conductivity of the carbon matrix and inhibits the diffusion of polysulfides and polyselenides, while the 3D mesoporous network facilitates fast electron and ion transport. Benefiting from the synergy between sulfur doping and 3D network architecture, the SeS2@ISMC composite displays a high reversible capacity of 486 mAh g(-1) after 200 cycles at 0.5 A g(-1) and outstanding rate capability of 465 mAh g(-1) at 4 A g(-1).
