The dissolution and shuttle behavior of lithium polysulfides has been considered to be one of the serious problems restricting the development of lithium−sulfur (Li–S) batteries. Polar compounds are regarded as promising sulfur host materials due to their strong chemical adsorption to lithium polysulfides. Herein, polar TiO[Formula: see text] with porous structure is employed as the sulfur host, which has a high specific surface area and provides nanoconfined space for storage and adsorption of sulfur species. As a result, the as-prepared S@TiO[Formula: see text] cathode exhibits significantly enhanced reversible capacity, cycling stability, and reaction kinetics compared to those of the as-prepared S@TiO2 cathode.

Lithium Sulfur

A porous TiO2 particle is synthesized and used as a sulfur host. The obtained TiO2 material provides a large number of pores that can accommodate sulfur, and the porous structure also enables effective contact between the host material and lithium polysulfides. The TiO2/S electrode shows excellent electrochemical performance, exhibiting a capacity loss of 0.17% per cycle and a Coulombic efficiency of 97.7% during cycling at 0.5 C. The appealing results are due to the porous characteristics of the TiO2 material and the chemical adsorption between the TiO2 and lithium polysulfides.

We developed a new nanowire for enhancing the performance of lithium-sulfur batteries. In this study, we synthesized WO3 nanowires (WNWs) via a simple hydrothermal method. WNWs and one-dimensional materials are easily mixed with carbon nanotubes (CNTs) to form interlayers. The WNW interacts with lithium polysulfides through a thiosulfate mediator, retaining the lithium polysulfide near the cathode to increase the reaction kinetics. The lithium-sulfur cell achieves a very high initial discharge capacity of 1558 and 656 mAh g−1 at 0.1 and 3 C, respectively. Moreover, a cell with a high sulfur mass loading of 4.2 mg cm−2 still delivers a high capacity of 1136 mAh g−1 at a current density of 0.2 C and it showed a capacity of 939 mAh g−1 even after 100 cycles. The WNW/CNT interlayer maintains structural stability even after electrochemical testing. This excellent performance and structural stability are due to the chemical adsorption and catalytic effects of the thiosulfate mediator on WNW.
