Abstract
Lithium-sulphur batteries are considered as some of the most potent secondary-battery systems. These batteries are expected to have extensive applications in fields requiring high-energy density. However, such applications are hindered by some serious intrinsic obstacles. Herein, TiO₂ nanosheets-rGO/sulphur (TiO₂ NS-rGO/S) composites were fabricated through a two-process hydrothermal method. TiO₂ nanosheets served as active sites for polysulphide absorption, whereas rGO offered space for sulphur improvement and TiO₂ NS-rGO/S composites. The TiO₂ NS-rGO/S composite exhibited high discharge capacity of 1099 mAh·g at 0.2 C rate and retained a capacity of 690 mAh·g after 100 cycles, with high sulphur loading of 3 mg·cm. The high initial specific discharge capacity and improved cyclic stability were attributed to the synergistic effects of TiO₂ nanosheets and rGO. These results indicated that the simple, low-cost and scalable method provides a novel perspective on practical utilisation of lithium-sulphur batteries.
