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.
