I/E Material

We produce high-quality information and electronic materials built on
chemical technology capabilities accumulated for over 50 years

LiBS

“ LiBS (Lithium-ion Battery Separator) SK innovation 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. ”

Aiming to Become a Global Top LiBS Manufacturer

Our research on microporous membranes has led us to obtain multiple patents since 1998. We began to operate the first commercial assembly line in November 2005, and have since developed and produced separators for various IT devices and heat-resistant separators for electric vehicle batteries in nine assembly lines. As we are not content with our current technology progress, we keep striving to develop more innovative product technologies. We aim to become a global top LiBS manufacturer.
