Abstract

Porous TiO₂ was prepared with metal-organic framework MIL-125(Ti) as template, and CNTs were introduced to form the three-dimensional conductive TiO₂/CNTs composite. The TiO₂/CNTs composite was coated on one side of the separator and applied in lithium-sulfur battery. The morphology and elemental composition of TiO₂ were characterized by transmission electron microscopy(TEM), scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS). The CNTs/S cathodes with TiO₂/CNTs composite coated separator deliver a high initial discharge capacity of 1051.1 mA•h/g and still retain a capacity of 904.8 mA•h/g after 150 cycles at 0.5C. Even at 1C, the capacity is still up to 1036.9 mA•h/g, and a high capacity of 763.0 mA•h/g is retained after 250 cycles, showing good rate performance.
