A defective MOF architecture threaded by interlaced carbon nanotubes for high-cycling lithium-sulfur batteries.

ABSTRACT: Metal organic frameworks (MOFs) have been deemed among the most promising sulfur hosts for lithium-sulfur (Li-S) batteries owing to their high specific surface areas, novel pore structures and open metal sites. However, their highly coordinated, electronically insulating and structurally unstable nature overshadows the merits of MOFs to a great extent. In this work, a novel UiO-66/carbon nanotube (UC) composite was initially synthesized via a facile one-pot synthesis strategy, in which abundant linker-missing defects were caused by introduced competitive coordination. Meanwhile, flexible and interlaced carbon nanotubes (CNTs) throughout mechanically stable UiO-66 nanoparticles constructed a reliable conductive network. Because of its superior structural stability, high electronic co
