Superconducting Organic Isolation Membrane (NKK-TF4030)

This product is designed for use in organic electrolyte supercapacitors, typically paired with neutral electrolytes. The NKK-TF4030 superconducting organic isolation membrane is a cellulose-based separator offering a thickness of 30 µm, engineered for low equivalent series resistance (ESR) applications. Its material composition and structural characteristics make it particularly suitable for button battery capacitors and other secondary battery manufacturing processes. Developed by NKK, the membrane is available in multiple sizes—ranging from small rolls (86 mm × 5 m) to larger continuous formats (86 mm × 500 m)—to accommodate different production scales. The TF4030 variant is optimized for organic system supercapacitors, where consistent ionic transport and reliable isolation between electrodes are critical. As a dedicated separator for energy storage devices, it supports stable electrochemical performance in non-aqueous electrolyte environments.
