  • Publication number: 20240021779
    Abstract: Provided is a method for manufacturing a lithium-sulfur battery cathode by using a fabric material, comprising the steps of: carbonizing a fabric material through heat treatment to manufacture a conductive support; electroplating a conductive metal material on the conductive support; loading, on the electroplated conductive support, a slurry comprising a sulfur polymer and a first carbon material replaced with a first functional group capable of hydrogen bonding to the sulfur polymer; and forming a capping layer by loading, on the conductive support, a second carbon material replaced with a second functional group capable of layer-by-layer self-assembling with the first carbon material.

  • Publication number: 20210230435
    Abstract: The present invention relates to a method for preparing silver nanoparticles and a method for producing an electrically conductive thin film by using the silver nanoparticles prepared by same, and provides a method which prepares hydrophobic silver nanoparticles having high distribution stability by being stabilized with tetraoctylammonium by processing with a thiosulfate salt, and which easily produces a thin film having high electrical conductivity, only by processing with a solution without post-processing under a high-temperature high-pressure condition, by using the hydrophobic silver nanoparticles stabilized with tetraoctylammonium.
