Lithium Sulfur

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.

Lithium Sulfur

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.
