3 - Dual-diameter 3-D nanofiber network coated with conductive thin film and its application as interlayer for Li-S battery

摘要

Disclosed is a dual diameter three-dimensional nanofiber network coated with a conductive thin film and a lithium-sulfur battery using the same as an intermediate electrode. A conductive thin film is coated on a nanofiber with a diameter even smaller than that of an existing conductive nanofiber and a nanofiber with a diameter larger than that of the existing conductive nanofiber by manufacturing nanofibers having dual diameter, coated with a conductive thin film. Therefore, the present invention provides a nanofiber having improved electrochemical properties and necessary properties as an intermediate of the lithium-sulfur battery by an enhanced surface area, improved porosity, and a surface control range.
