How does the 125 μm thickness of the N-115 membrane contribute to vanadium ion blocking and mechanical durability in flow battery applications?
The N-115 membrane's 125 μm thickness and 246 g/m² basis weight provide maximum mechanical durability and vanadium resistance. With tensile strength ≥30 MPa and elastic modulus ≥400 MPa, it withstands extreme operating conditions while minimizing vanadium crossover.
What are the critical ion-exchange properties of the N-115 membrane for vanadium flow battery operation?
The membrane maintains an acid capacity of 1.00±0.05 meq/g and in-plane conductivity ≥0.100 S/cm, with normal conductivity ≥0.04 S/cm. Water content is 5.0±3.0% and water uptake is 50.0±5.0%, ensuring stable electrochemical performance in vanadium redox flow batteries.
Can the N-115 membrane be supplied in custom sizes and what information is required for a quotation?
The standard sheet size is 1 m × 1 m (1 m²). Custom dimensions are available upon request; customers must include desired dimensions in their email inquiry to receive a quotation. Standard packaging ensures membrane protection during transit.
The N-115 membrane (125 μm, 246 g/m²) delivers superior vanadium blocking and mechanical ruggedness for demanding flow battery stacks, though its thick profile increases ionic resistance and requires specific hydration management.
Positive
- Extra-thick mechanical durability: At 125 μm and 246 g/m² basis weight with tensile strength ≥30 MPa and elastic modulus ≥400 MPa, this membrane provides maximum resistance to mechanical stress and vanadium crossover in extreme operating conditions.
- Stable electrochemical performance: Acid capacity of 1.00 ± 0.05 meq/g combined with controlled water uptake (50.0 ± 5.0%) and water content (5.0 ± 3.0%) ensures consistent proton conductivity and minimal dimensional swelling in flow battery environments.
Trade-offs
- Increased ionic resistance trade-off: The 125 μm thickness reduces in-plane conductivity to ≥0.100 S/cm and normal conductivity to ≥0.04 S/cm, requiring higher membrane area or operating voltage to compensate for greater ohmic losses compared to thinner grades.
- Hydration sensitivity for performance: With a narrow water content tolerance of 5.0 ± 3.0% and water uptake of 50.0 ± 5.0%, the membrane must be operated within a controlled hydration window; deviations can alter ionic conductivity or mechanical integrity.
