SuFExable polymers with helical structures derived from
Aug 16, 2021· Sulfur(vi) fluoride exchange (SuFEx) is a category of click chemistry that enables covalent linking of modular units through sulfur(vi) connective hubs.
Jan 26, 2021· The SEC curve of the isolated polymer after reaction time of 1 d, P1-µW, exhibited an average M w of 4400 g mol −1 (Đ = 2.1) with almost identical intensities in the lower molar mass region, i.e., high retention time (compare Figure 1A), proving the efficiency of µW-assisted polymerization. Noteworthy, the scalability of µW-induced
Aqueous zinc-organic polymer battery with a high rate
The application of a conjugated polymer with 9,10-di(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene (exTTF) units as cathode and zinc as anode enables an aqueous-based hybrid organic battery. This
The invention provides a method for improving the dispersibility of insoluble sulfur, characterized by adding a high polymer material coating agent in the drying process of preparation of the insoluble sulfur to carry out coating on IS powder, wherein, the high polymer material is added in the IS powder through dissolving with a solvent, and the addition of the high polymer

Coral-like CoP hollow composites as effective host
Lithium-sulfur batteries (LSBs) have been generally acknowledged to be one of the most promising candidates for the next-generation energy storage systems, due to their high specific capacity (1675 mAh/g) of the sulfur cathode, low cost, environmental friendliness, and natural abundance of sulfur resources [1, 2].However, they suffer from several scientific and

History and recent developments in divergent electrolytes
Lithium–sulfur batteries, with a high specific capacity, low cost and environmental friendliness, could be investigated as a next-generation energy-storage system. However, the limitations of lithium–sulfur batteries in capacity retention are directly related to the role of the electrolyte. Recently, most of Popular Advances
In order to explore the potential application of sulfur in aqueous rechargeable batteries, core-shell sulfur-polypyrrole (S@PPy) composites were prepared through a novel one-pot and surfactant-free method. Sulfur exhibits a very high capacity of 473 mA h g(-1) and good cycling...
