  • Publication number: 20260081159
    Abstract: A sulfur electrode and a method for manufacturing the same are disclosed. The method for manufacturing the sulfur electrode includes: growing carbon fibers on a surface of stainless steel; connecting the stainless steel on which the carbon fibers are grown to a cathode of a current controller in an aqueous solution in which sulfur ions are dissolved; and forming a sulfur thin film on each of surfaces of the carbon fibers grown on the surface of the stainless steel and in each of spaces between the carbon fibers by controlling a current of the current controller.

  • Publication number: 20240387796
    Abstract: A composite sulfide electrode and a manufacturing method therefor are disclosed. A method for manufacturing a composite sulfide electrode comprises the steps of: preparing a mixed solution of polyacrylonitrile (PAN) and a metallic oxide; stirring the prepared mixed solution; electrospinning the stirred mixed solution to prepare a wire-type precursor bearing a metallic oxide in PAN; drying the prepared wire-type precursor; mixing the dried wire-type precursor and a sulfur powder; and injecting a gas to the mixture of the wire-type precursor and the sulfur powder to sulfurize the wire-type precursor.
