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.
Claims8
A manufacturing method for a composite sulfide electrode, the method comprising:
- producing a mixed solution of polyacrylonitrile (PAN) and a metal oxide;
- stirring the produced mixed solution;
- electrospinning the stirred mixed solution to produce a wire type precursor including the metal oxide in PAN;
- drying the produced wire type precursor;
- mixing the dried wire type precursor and sulfur powder;
- and
- thermally treating a mixture of the wire type precursor and the sulfur powder to sulfurize the wire type precursor.
