摘要: A laminated polyester film according to the present invention comprises: a core layer; and a sub-layer laminated on at least one surface of the core layer and containing a first particle and a second particle which are different components, wherein an average diameter of the first particle is 6 to 20 times of an average diameter of the second particle. Types, different properties, sizes, and contents of the first particle and the second particle are adjusted to solve the image blurring phenomenon and prevent a winding fault generated during processing and winding a final product. Therefore, workability and perfection of a final product can be increased and the defect rate can be decreased.

摘要: Disclosed are a micropore-filled amphoteric membrane for low vanadium ion permeability, a method of manufacturing the same, and a vanadium redox flow battery including the amphoteric membrane. The micropore-filled amphoteric membrane for low vanadium ion permeability minimizes crossover of vanadium ions, which occurs between a catholyte and an anolyte in a redox flow battery, and has low membrane resistance and thus has remarkably improved performance as compared to commercially available ion-exchange membranes such as Nafion, and accordingly, can be effectively used in the manufacture of a redox flow battery. In addition, the micropore-filled amphoteric membrane is continuously manufactured through a roll-to-roll process, and thus the manufacturing process is simple and manufacturing costs can be greatly reduced.
