Lithium Sulfur

It is of great importance to develop high-quality carbon/sulfur cathode for lithium-sulfur batteries (LSBs). Herein, we report a facile strategy to embed sulfur into interconnected carbon nanoflake matrix forming integrated electrode. Interlinked carbon nanoflakes have dual roles not only as a highly conductive matrix to host sulfur, but also act as blocking barriers to suppress the shuttle effect of intermediate polysulfides. In the light of these positive characteristics, the obtained carbon nanoflake/S cathode exhibit good LSBs performances with high capacities (1117[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 0.2[Formula: see text]C, and 741[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 0.6[Formula: see text]C) and good high-rate cycling performance. Our synthetic method provides a novel way to construct enhanced carbon/sulfur cathode for LSBs.

The rechargeable lithium-sulfur batteries were investigated as the most promising energy storage system. Although the composites of carbonaceous materials and metal oxides as the hosts of sulfur have been applied to improve the performance, their structures usually collapsed due to huge volumetric expansion of sulfur. Therefore, interlayer reported as a novel cell configuration could efficiently restrict the shuttle effect of polysulfide. Here, we design a unique separator modified by a functional “polysulfide trapping net” which consists of intertwined TiO2 nanotubes and carbon nanotubes to improve the electrochemical performance of lithium sulfur batteries. Benefiting from the network structure, there are abundant ion pathways, meanwhile, TiO2 nanotubes provide strong chemical and physical adsorption, carbon nanotubes serve as a conductive network which accelerates the transport of electrons. With the modified separator, the electrode exhibits an initial capacity of 936[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 1[Formula: see text]C rate and maintains a stable cycling performance over 200 cycles.
