DMSO/DMF co-solvent precipitated nano-sulfur cathode for highly loading lithium-sulfur pouch cells Open
We employ a simple anti-solvent precipitation method to prepare sulfur nanoparticles. Dimethyl sulfoxide (DMSO) and N,N-dimethylformamide (DMF) are chosen as co-solvents, and cetyltrimethylammonium bromide (CTAB) is used as a stabilizer. B…

Reduced graphene oxide participation enabling fast nano-homogeneous deposition of sulfur for lithium–sulfur battery cathode Open
We present a facile, rapid, and gentle approach to synthesize a cathode for lithium-sulfur batteries utilizing reduced graphene oxide (rGO). The rGO sheets are introduced into a supersaturated sulfur solution, resulting in the uniform crys…

Rapid Yet Efficient Reduction of Graphene Oxide Triggered by Semi‐Molten Metals Open
Reduced graphene oxide (rGO) has garnered extensive attention as electrodes, sensors, and membranes, necessitating the efficient reduction of graphene oxide (GO) for optimal performance. In this work, a swift reduction of GO that involves …
