Abstract: Provided is a bioresorbable stent including a stent substrate including a bioresorbable polymer and a contrast medium containing an iodine component, coated on the stent substrate. Since the stent according to the present invention is absorbed in and removed from the human body after a predetermined time, it has excellent biodegradability since it has improved radiopacity by iodine contrast medium coating, it has a high radiography contrast and is very efficient even when a procedure is performed with real time radiography, and since it has low foreshortening and high flexibility, radial force, and re-coil, it may be useful for insertion into a blood vessel having a small diameter, an acute occlusive lesion, an imminent occlusive lesion, and the like.

Abstract: The present disclosure relates to a method of recycling a positive electrode active material and a recycled positive electrode active material prepared by the same. More particularly, the present disclosure relates to a method of recycling a positive electrode active material, the method including step A of fragmenting a waste battery including a positive electrode, a separator, and a negative electrode to form waste battery scraps; step B of removing the negative electrode by jetting compressed air onto the waste battery scraps; and step C of treating the waste battery scraps from which the negative electrode has been removed with a solvent to remove the separator and obtain positive electrode scraps, and a recycled positive electrode active material prepared by the method.

Abstract: Provided is a method for recovering and reusing an active material from a positive electrode scrap.

Abstract: The present invention relates to an apparatus and a method for inspecting battery cells for automation of total inspection. To this end, the present invention is configured such that test objects are sequentially stacked on a test object casing provided on an upper portion of a mounting stage of a main stage, images of the test objects are obtained by radiography after the test object casing is moved to a test object inspection unit, and the test objects stacked on the test object casing are unloaded to the outside after the images are obtained. Accordingly, the present invention enables total inspection to be performed on battery cells, which are the test objects, in order to quickly divide good and defective products, and solves a delay of a flow rate caused by X-ray inspection of the test object inspection unit in order to improve productivity and efficiency.
