SPEEK flow, 14.5mS/cm

- Transparent SPEEK with 40/75um thickness, offering clear visual inspection during cell assembly and operation.
- Sulfonation degree of 60% delivers ionic conductivity of 14.5 mS/cm, ensuring efficient proton transport for stable .
- Tensile strength of 24-28 MPa and fracture elongation of 28-32% provide robust mechanical integrity for long-term cycling.
- Non-fluorinated devise reduces environmental concerns while maintaining selectivity and chemical resistance in acidic electrolytes.
- Compatible with common flow systems, including vanadium redox and zinc-bromine configurations, for lab or -scale testing.
