N2 - 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 TiO2-x 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@TiO2-x cathode exhibits significantly enhanced reversible capacity, cycling stability, and reaction kinetics compared to those of the as-prepared S@TiO2 cathode.
