2325 Separator Roll 100mm × 10m, 25 µm PP/PE/PP — Battery Separator for Na-ion / K-ion / Li-ion / Li-S Cell R&D
2325 spec PP/PE/PP trilayer microporous separator roll, 25 µm thickness, 39% porosity, 0% TD shrinkage. Cut φ18/19/24 mm discs in-lab for CR2032/2025/2016 coin cell, pouch, and 18650 cylindrical cell R&D. Compatible with Na-ion / K-ion / Li-ion / Li-S battery systems.
The LabCore **\*\*Separator 2325\*\*** is a **\*\*25 µm PP/PE/PP trilayer microporous membrane\*\*** manufactured by a dry-stretched process, **\*\*purpose-built for laboratory-scale, multi-chemistry battery research\*\***. The PP outer layers deliver oxidation resistance and cycling stability; the PE inner layer provides thermal shutdown. Transverse-direction shrinkage is held to ≤0% @ 90 °C/1h — a safety-critical spec that suppresses internal shorts during high-temperature cycling. The 39±5% porosity balances ion transport and mechanical strength. Each roll is 100 mm wide × 10 m long, yielding \~390 φ18 mm discs — enough for 6–12 months of typical lab use.
