SELEMION™ Anion Exchange Membranes (AEMs), developed by AGC Engineering (formerly Asahi Glass), are a globally recognized family of hydrocarbon-based ion-exchange materials. Unlike fluorinated membranes (like Nafion), SELEMION membranes utilize a poly(styrene)-based structure, making them more cost-effective and highly versatile for industrial liquid processing.
There are four main types of SELEMION™ anion exchange membranes: AMVN, DSVN, AAVN, and ASVN. The main applications for SELEMION™ AEM is electrodialysis (ED), which uses alternating stacks of anion and cation membranes to move salts from a "desalination" chamber to a "concentration" chamber using DC current. The second application is redox flow battery, SELEMION membranes (specifically the DSVN and AMVN grades) are popular in Aqueous Organic Redox Flow Batteries (AORFBs) and Vanadium systems.
