W-SCOPE Corporation engages in the production and distribution of advanced film solutions in Japan. The company primarily develops and provides high-performance separators essential for lithium-ion secondary batteries, alongside specialized ion exchange membranes, leveraging its proprietary polymer film technology. These products, including bare film and ceramic-coated separators crafted with environmentally conscious water-based slurries, are distributed across a global client base, including South Korea, the United States, and Europe. Established in 2005, the firm is headquartered in Tokyo, Japan, and maintains a strategic focus on continuous innovation in green membrane technology, aspiring to lead the global separator market. In a recent strategic adjustment, the company transitioned its W-SCOPE CHUNGJU PLANT subsidiary to an equity-method affiliate in November 2024.
