Alkaline anion exchange membrane 40μm AEM

 LiMo Technology is committed to solve the problem of bottle-neck in the field of new energy membrane materials, and has realized the production of anion exchange membrane (AEM) with high alkaline stability.

Compared with state-of-the-art AEMs, LIMO-AEM has better comprehensive performance, including high alkaline stability, high ionic conductivity, low resistance, high mechanical strength, and high dimensional stability. It is suitable for working at high temperature and in high alkaline concentrated solution. AEM is widely used in fuel cells, hydrogen production by water electrolysis, CO₂ reduction, redox flow batteries, lithium ion extraction, waste acid recovery, seawater desalination by osmotic power generation and other fields.
