Polyacrylonitrile (PAN) precursors have been polymerized at different radical polymerization temperatures for preparing sulfurized-polyacrylonitrile (S-PAN) composite cathodes in rechargeable lithium sulfur battery. The physical properties of these composites have been investigated using X-ray diffraction, Fourier transform infrared spectrometry, Raman spectroscopy, Brunner-Emmet-Teller measurement and Gel permeation chromatography analysis. The electrochemical performance of the S-PAN composite cathodes made from the PAN precursor was investigated. The results showed that the molecular weight distribution of the PAN precursors affected the electrochemical performance of the S-PAN made from the PAN precursor. S-PAN composites derived from PAN with a narrower molecular weight distribution at 65 °C were exhibit the best electrochemical performance in lithium-sulfur battery.

The effect of mixed electrolytes and organic additives on the electrochemical performance of rechargeable lithium/sulfur battery is investigated. The mixture of organic electrolytes, DME, DIG, TEGDME, and DIOX, was prepared to have appropriate composition, and to the electrolyte were added various organic additives, such as toluene, γ-butyrolactone, and MA. They showed an improved cyclic efficiency of lithium/sulfur battery and made utilization of active material, sulfur, more effective.

Lithium sulfur batteries (LSBs) have been one of the most promising second batteries for energy storage. However, the commercialization of LSBs is still hindered by low sulfur utilization and poor cycling stability, resulting from shuttle effect and low redox kinetics of lithium polysulfides (LiPSs). Significant progress has been made over the years in enhancing the batteries performances and tap density with the transition-metal sulfides as sulfur host or additive in LSBs. In this review, we present the recent advances in the use of various nanostructured transition-metal sulfides applied in LSBs, and also focus on the interaction mechanisms of polar transition-metal sulfides with LiPSs and its catalysis for the redox of LiPSs. It may provide avenues for the application of transition-metal sulfides in LSBs. The challenges and perspectives of transition-metal sulfides are also addressed.
