Li-S (Li-S) batteries are strongly considered as next-generation energy storage systems because of their high energy d. However, the shuttling of Li polysulfides (LiPS), sluggish reaction kinetics, and uncontrollable Li-dendrite growth severely degrade the electrochem. performance of Li-S batteries. Herein, a dual-functional flexible free-standing C nanofiber conductive framework in situ embedded with TiN-VN heterostructures (TiN-VN@CNFs) as an advanced host simultaneously for both the S cathode (S/TiN-VN@CNFs) and the Li anode (Li/TiN-VN@CNFs) is designed. As cathode host, the TiN-VN@CNFs can offer synergistic function of phys. confinement, chem. anchoring, and superb electrocatalysis of LiPS redox reactions. Meanwhile, the well-designed host with excellent lithiophilic feature can realize homogeneous Li deposition for suppressing dendrite growth. Combined with these merits, the full battery (denoted as S/TiN-VN@CNFs || Li/TiN-VN@CNFs) exhibits remarkable electrochem. properties including high reversible capacity of 1110 mA-h g-1 after 100 cycles at 0.2 C and ultralong cycle life over 600 cycles at 2 C. Even with a high S loading of 5.6 mg cm-2, the full cell can achieve a high areal capacity of 5.5 mA-h cm-2 at 0.1 C. This work paves a new design from theor. and exptl. aspects for fabricating high-energy-d. flexible Li-S full batteries.
