NanoPorous Films (NPF)
- LiSO NPFs are wettable, alongside excellent thermal and chemical stabilities; and yet, provide dual safety features, i.e., low and high Tm's of 130 to 400oC; thereby, unparalleled in cycling and safety performance.
- Existing polyolefin (PE and PP) BSFs are unwettable to electrolytes with a low Tm of 160oC or less; thus, poor in performance and safety.
- Nonwoven separators (NWV) can provide a high Tm of 250oC, but thick, fragile, nonuniform, high cost, and yet substantially low in strength and chemical resistance.
Sorbent Membranes (SBM)
LiSO SBMs can be made of a wide range of materials, compositions and structures at high productivity. SBMs deliver: i) superior sorption kinetics and capacity; ii) excellent permselectivity towards gases, CO2, volatile, fluids and water; iii) exceptional strength and adhesion; iv) wettability toward polar and nonpolar substrates, and v) little pressure drop of analytes across the products.
SBMs exhibit superior layer adhesion, designed through interdiffusion of dissimilar molecules at interfaces. The layer boundaries are characterized by: i) co-mingling components diffused across the interfaces during the lamellar flow and ii) stress-induced interlocking in-situ of such interdiffused molecules during the extensional flow.
UltraHigh Barrier Films (UHB)
- Clear and Metallized (MET) Packaging Films, etc.
- Photovolatic (PV) Encapsulants & UltraWeatherable Backsheets
- Flexible Electronics
- Current Collectors for Energy Storage Devices
- LiSO Met-BOPP: Metallized oriented polypropylene films (Met-BOPP) will undergo no metal cracks and thus, no barrier degradation during use or post-film converting processing under substantive tension.
- Existing BOPP: Commercial high and ultrahigh Met-BOPP films suffer greatly from poor metal adhesion, metal cracks and barrier degradation.
