  • Designed as ion exchange membranes for redox flow batteries

Product Description

LINQCELL VRB-AEM50 is a 50-µm partially fluorinated anion exchange membrane without reinforcement. It has low ohmic resistance, excellent mechanical properties, low water uptake, and minimal dimensional swelling. VRB-AEM50 has high oxidative stability, resists chlorine, and remains stable in acidic environments (pH > 4). The recommended operating temperature is from room temperature to 50 °C.

LINQCELL VRB-AEM50 is highly suitable for electrochemical applications that require exceptional oxidative stability and chlorine resistance, such as redox flow batteries operating with very harsh, aqueous acidic solutions.

Key Features and Benefits:

  • Low Resistance: Facilitates efficient ion transport, minimizing energy losses and maximizing device performance.
  • High Vanadium Ion Blocking Capability: Significantly reduces vanadium crossover in Redox-Flow Batteries, ensuring prolonged operational lifespan and enhanced efficiency.   
  • High Acidic Stability: Maintains its integrity and performance in harsh acidic conditions, crucial for applications like Vanadium-Redox-Flow Batteries (VRBs).

Highly Recommended for:

  • Vanadium-Redox-Flow Batteries (VRBs)
  • Aqueous Acidic Redox-Flow Batteries.

LINQCELL VRB-AEM50 comes in different sizes to meet various device design requirements. Contact us for custom sizes or other specific requirements.

Mechanical Properties
Tensile Strength
Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can withstand while being stretched or pulled before failure.

Some materials break very sharply, without plastic deformation, in what is called a brittle failure. Others, which are more ductile, including most metals, experience some plastic deformation and possibly necking before fracture.
Tensile Strength
Tensile Strength
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.
 30 MPa
