Semi-Permeable Membranes TRIZ Cases
- Lithium Hydroxide Recovery via Li-Selective Membrane Crystallization
A Li-selective membrane isolates lithium from battery recycling extracts, enabling lower-energy crystallization of high-purity lithium hydroxide.
- Electrolyte Membrane Polymer Without Ether Bonds for Alkaline Durability
An ether-free aromatic polymer improves alkaline chemical durability, membrane strength, and formability for fuel cells and water electrolysis.
- CO2 Separation Membrane Pressure Control Using Water Vapor Sweep
Controlling permeate pressure and temperature lets feed-side water vapor create a sweep effect, boosting CO2 permeation with lower energy use.
- Fluoropolymer Composite Separator Films for Low-Temperature Ionic Conductivity
Dense pore-free fluoropolymer composite films improve separator ionic conductivity below 80°C while preserving extrusion-based manufacture.
- Composite Ammonia Membrane Reactor for High-Purity Hydrogen
A Pd/BCC composite membrane separates hydrogen during ammonia dehydrogenation, cutting purification steps, reactor volume, and durability issues.
- Hollow Fiber Membrane Extraction for Selective Li-Ion Metal Recovery
Immobilized organic phases in hollow fibers recover cobalt, nickel, manganese, and lithium from spent cathodes without emulsions or high solvent inventory.
- Microlayer Battery Separators for Strength and Shutdown Balance
Co-extruded microlayer separator membranes improve puncture strength, shutdown behavior, split resistance, and dielectric breakdown in lithium-ion batteries.
- Freeze-Cast Ceramic Membrane with Zoned Pores for High-Flow Filtration
Directional freezing creates zoned dendritic pores that preserve throughput while improving particle capture across different sizes.
- Fluoropolymer Hybrid Composite Films for Low-Temperature Battery Separators
Extruded fluoropolymer hybrid films combine inorganic phases and metal salts to raise separator ionic conductivity below 80°C.
- Acid-Base Polymer Blend Membranes for Low-Resistance Ion Separation
A halogen-free acid-base polymer blend membrane cuts electrical resistance and electrolyte crossover while maintaining ion conduction in redox flow batteries.
