In an article, author is Quezada-Miriel, Magdalena, once mentioned the application of 135-57-9, SDS of cas: 135-57-9, Name is Bis(2-benzamidophenyl) Disulfide, molecular formula is C26H20N2O2S2, molecular weight is 456.5792, MDL number is MFCD00043806, category is amides-buliding-blocks. Now introduce a scientific discovery about this category.
Lithium-sulfur (Li-S) batteries are considered promising energy-storage devices owing to the high specific capacity and low cost of the S cathode. However, they suffer from capacity decay and poor coulombic efficiency arising from the dissolution of long-chain polysulfides and their shuttling. A facile and scalable method was developed to directly coat a thin (approximate to 57.3 nm) and porous polyamide (PA) interlayer onto a S cathode by interfacial polymerization. This PA interlayer prevented the shuttling of polysulfides by creating a physical barrier and, through chemical interactions between the amide functionalities of PA and the polysulfides, allowing access to the S electrode by the Li ions. The resulting PA-coated cathode exhibited approximately 64.2 % capacity retention over 1000 cycles at 1 C with only 0.0358 % decay per cycle and a moderate capacity of 1008 mAh g(-1) at 0.1 C.
