5/5
Model Number: M-PEC-20
Material: PE base film
Coating: Ceramic coated
Our ceramic lib separator is the essential material for lithium-ion batteries (LIB) which has been used in the broad fields of LIB application for many years.
Feature:
Improved Battery Safety
Longer Battery Cycle Life
Higher Battery Performance
M-PEC series ceramic-coated lib separator is fabricated of PE base film, and their surface is coated with a nano-scale Al2O3 layer. After special chemical printing treatment, the Al2O3 material is printed on the surface of the base film, which significantly improves the high-temperature stability of lithium-ion batteries and enhances battery safety. M-PEC series products are one of the safest and most durable battery separator solutions for high-power performance lithium-ion batteries.
