“ LiBS (Lithium-ion Battery Separator) SK ie technology is the first in Korea and the third in the world to exclusively develop separators,
a key component in lithium-ion batteries, by applying chemical technologies accumulated over the span of 50 years and advanced nano-technologies ”

To become the best LiBS Manufacturer in the world

Since its first technical research in 1998, we have continuosly developed technology and obtained multiple patents.
Ever since we succeeded in the first commercial operation in 2005,
we are now developing and providing separotors for IT devices and EV batteries from 17 production lines(as of MAR 2021) at home and abroad.
However, we do not satisfied with the current status, but only strive for the technical innovations which in the end will lead us to be the best LiBS manufacturer in the world.
