Abstract: Proposed is a wind turbine blade with a lightning protection receptor. The wind turbine blade with a lightning protection receptor is a technology that allows for excellent lightning capture rate for both negative and positive lightning by improving lightning measures for conventional wind turbines, which are vulnerable to positive lightning, in line with the increasing wind turbine heights for large-scale power generation and the trend toward offshore wind power, and that minimizes post-repair/supplementary measures by limiting blade damage/coating peeling due to lightning strikes to a narrow area, unlike in the conventional case where damage or peeling of the coating occurs over the entire area of a blade when struck by lightning on an edge wire inserted into the lateral inner side of the blade.

Abstract: In a method for preparing lithium sulfide, a solid sulfur layer and a lithium source layer are sequentially arranged in a reactor. A gas feed is injected into the reactor in a single direction to obtain a lithium sulfide-containing product. The lithium sulfide-containing product is dissolved in an anhydrous solvent to form a lithium sulfide-containing solution. Lithium sulfide is separated from the lithium sulfide-containing solution. The gas feed sequentially passes through the solid sulfur layer and the lithium source layer, such that high-purity lithium sulfide may be efficiently prepared.
