英文摘要	Selenium disulfide (SeS2) possesses competitive advantages over pure sulfur or selenium as an electrode material for lithium storage. However, the shutting effect and slow conversion rate of soluble lithium polysulfides/polyselenides (LiPSs/LiPSes) compromise the practical application of Li-SeS2 batteries. Herein, a ZIF-67@PAN-derived Co-N-C@C multifunctional porous membrane as the LiPSs/LiPSes trapping barrier for Li-SeS2 batteries is proposed. The hierarchical porous conductive network facilitates the transport of electrons/lithium ions. Meanwhile, the Co-N-C architecture not only has chemical interaction for trapping the mobile LiPSs/LiPSes, but also catalyzes the LiPSs/LiPSes conversion reaction during the cycling process. Benefiting from the multifunctional capabilities, the constructed Li-SeS2 cells with the aforementioned interlayer exhibit a high capacity utilization of 978 mAh g(-1) at 0.2 A g(-1), together with an excellent rate capacity of 532 mAh g(-1) at 3 A g(-1) and also superior cycle life with a capacity of 557 mAh g(-1) after 300 cycles at 1 A g(-1). More strikingly, they show promising capacity with stable cell performance with a mass loading of 4 mg cm(-2).
