This cellulose diaphragm roll requires continuous-format processing equipment to avoid mechanical damage from repeated handling. Its pH neutrality (5.5-8.0) and controlled air permeability ensure compatibility with common battery electrolytes.
- pH Range Constraint: The pH range of 5.5-8.0 minimizes chemical interaction with electrolyte systems.
- Air Permeability Constraint: Air permeability of 80-150s/100ml ensures balanced ion transport without short-circuit risk.
- Tensile Strength Requirement: Tensile strength above 7.8N/15mm is necessary to withstand winding tension during electrode assembly.
- Dimensional Tolerance: Thickness tolerance of 27.6-32.4μm must be maintained to prevent uneven compression in stacked cells.
- Electrolyte Compatibility: Cellulose material is chemically compatible with both battery electrolytes and supercapacitor systems to avoid degradation.
How does the air permeability range of 80-150 s/100ml in the Atomfair Cellulose Diaphragm Roll affect its ion transport efficiency versus mechanical robustness?
The air permeability range directly correlates with ionic conductivity; lower values indicate higher porosity and faster ion transport but may marginally reduce mechanical density. However, the diaphragm maintains a tensile strength >7.8N/15mm and a density of 0.35-0.45 g/cm³ across the entire 80-150 s/100ml range, ensuring structural integrity while enabling efficient ion conduction for balanced isolation and transport.
Is the Atomfair Cellulose Diaphragm Roll compatible with organic electrolytes commonly used in lithium-ion batteries?
Yes, the cellulose-based material is chemically compatible with battery electrolytes, including organic electrolytes typical in lithium-ion systems, as stated in the product overview. Its neutral pH range of 5.5-8.0 and ISO 14001 certification ensure no adverse reactions with standard electrolyte formulations, supporting diverse energy storage R&D and production scenarios.
What are the recommended storage conditions for the Atomfair Cellulose Diaphragm Roll to prevent degradation?
The cellulose diaphragm should be stored in a cool, dry environment away from direct sunlight to preserve its mechanical properties and chemical stability. With a neutral pH range of 5.5-8.0 and tensile strength >7.8N/15mm, the material resists degradation under normal handling, but minimized moisture exposure is recommended as cellulose is hygroscopic. The roll format facilitates continuous processing in automated assembly lines.
This cellulose diaphragm roll provides broad chemical compatibility with battery electrolytes and supercapacitor systems, alongside optimized pore structure for balanced ion conduction and electron blocking. However, its roll-only format necessitates unwinding and cutting equipment, and the 27.6–32.4 µm thickness window may require individual measurement for applications demanding strict uniformity.
Positive
- Broad Electrolyte Compatibility: Cellulose material is chemically compatible with both battery electrolytes and supercapacitor systems, supporting diverse energy storage R&D and production without adverse reactions.
- Balanced Ion Transport and Isolation: Optimized air permeability (80–150 s/100 ml) and porous structure enable efficient ion transport between electrodes while blocking electron flow, preventing short circuits and improving energy conversion efficiency.
Trade-offs
- Roll-Only Format Limits Modular Use: The diaphragm is supplied only in continuous roll form (500 m × 60 mm), requiring unwinding, cutting, and handling equipment that may not be readily available in small-scale or manual assembly setups.
- Thickness Tolerance Window Requires Calibration: Nominal thickness is 30 µm with a range of 27.6–32.4 µm; devices with strict separator thickness requirements may need individual piece measurement or process adjustment to ensure uniformity.
