Structural And Electronic Properties

Carbon nanotubes (CNTs) possess excellent structural and electronic properties and have been widely investigated as anode materials. Covalent modification of carbon nanotubes (CNTs) with organosilica-containing polyoxometalate (POM) leads to the formation of the nanocomposite CNTs–SiW11 with high discharge capacity, good capacity retention and cycling stability.

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-1 at 0.2 C rate and retained a capacity of 690 mAh·g-1 after 100 cycles, with high sulphur loading of 3 mg·cm-2. 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.
