ADVANCED DEVELOPMENT STAGE:
Celgard® CyclePlus™ Cycle Improved Ceramic Coated Separators mitigate the effects of contamination and cathode transition metal dissolution to increase capacity retention and cycling uniformity at module level.
Internal metal contamination tests using single-layer pouch cells show significant improvement over traditional ceramic coated separators.
Third Party Test Conditions:
Contamination metal used: Proprietary to 3rd party tester.
Cathode chemistry: NMC532 2 Ah cylindrical
OCV-1: 24 h storage at RT
OCV-2: 36 h storage at 45C + 24 h storage at RT

ADVANCED DEVELOPMENT STAGE:
Celgard® DuraWet™ Enhanced Wettability Separators:
- Improve electrolyte filling and soaking speeds, enhance long-term electrolyte retention and decrease cell scrap
- Enhance battery cycle life
- Enable low temperature battery applications
Initial testing shows an average decrease in electrolyte-separator contact angle as well as in separator electrical resistance by up to 30% relative to other polyolefin membranes.
Control 1 and 2 separators are representative of ceramic coated and non-coated polyolefin (wet/dry) microporous membranes.
