Abstract: A winder for an electrode assembly of a rechargeable battery for improving space usage is disclosed. The winder includes a plurality of spools supplying a negative electrode member, a positive electrode member, a first separator member, and a second separator member, a mandrel stacking and spirally winding the first separator member, the negative electrode member, the second separator member, and the positive electrode member supplied by the spool, a first frame accommodating a predetermined number of spools from among the plurality of spools and the mandrel, a second frame connected to the first frame and accommodating other spools from among the plurality of spools, a reorienter installed between the first frame and the second frame and reorienting a progressing direction of one of the members, and a position controller controlling a position of the member that passes through the reorienter and progresses towards the mandrel.

Abstract: A sealing member, a photoelectric conversion device having the same, and a method of preparing the same are disclosed. In one aspect, the sealing member for the photoelectric conversion device joins a first substrate and a second substrate, which face each other, and seals an electrolyte solution in a space therebetween. An edge of the sealing member may include a rounded portion and a radius of a circle including the rounded portion is about 50% or more of the width of the sealing member. The sealing member may serve to reduce leakage of the electrolyte solution due to lowered adhesion of the sealing member or a wrinkled sealing member, and thus, improve reliability of the photoelectric conversion device.
