Battery Polyethylene (PE) Separator Film
Generic low cost separator used in separating lithium ion battery cathode and anode. Lower melting point that more common PP separators which may be beneficial in some cases with self shutting cells. Standard roll 85mm x 60m, custom sizes on request.
Product characteristics:
1. Uniform pore size distribution
2. Low obturator temperature
Used in separating lithium ion battery cathode and anode. Lower melting point that more common PP separators which may be beneficial in some cases with self shutting cells. (Please be aware that 3 layer PP/PE/PP separators are also available, check Celgard 2320 and Celgard 2325)
